The existing community client ([lunaetco/spicedb-client](https://github.com/lunaetco/spicedb-client)) may be stale, incomplete, or insufficiently idiomatic. This project delivers a standalone Rust library crate (`prescience`) that wraps the full SpiceDB gRPC API with strong types, ergonomic builders, and first-class async support — giving Rust teams a dependency they can confidently ship to production. + +--- + +## Users & Actors + +| Actor | Description | Key Needs | +|---|---|---| +| **Rust backend developer** (primary) | Integrates SpiceDB permission checks into application services | Ergonomic API, strong typing, clear error handling, good docs | +| **Platform / DevOps engineer** (secondary) | Manages SpiceDB schemas and bulk-loads relationships | Schema read/write, bulk import/export, watch for changes | +| **SpiceDB server** (external system) | Exposes gRPC API (v1) on a configured endpoint | Stable protobuf contract defined in `authzed/api` | + +No UI actors. No end-user-facing surface. This is a library consumed programmatically. + +--- + +## Functional Requirements + +### FR-1: Client Construction & Connection + +1. **FR-1.1** — The library MUST provide a client constructor that accepts a SpiceDB endpoint (URI) and a bearer token. +2. **FR-1.2** — The constructor MUST support TLS-encrypted connections. TLS is determined by URI scheme: `https://` = TLS enabled, `http://` = plaintext. The builder provides a `.tls(bool)` override for explicit control. +3. **FR-1.3** — The constructor MUST support plaintext/insecure connections (explicit opt-in) for local development. Attempting `http://` to a non-loopback address without explicit `.insecure(true)` on the builder MUST return `Err(Error::InvalidArgument(...))` with a message indicating that insecure connections to remote addresses require explicit opt-in. No warning-log-and-proceed behavior. (Rationale: fail-closed is safer. Consistent with the error-handling approach.) +4. **FR-1.4** — The client MUST reuse the underlying `tonic::Channel` across calls (connection pooling via channel reuse). +5. **FR-1.5** — The client SHOULD accept an externally-constructed `tonic::Channel` for advanced use cases (custom interceptors, load balancing, custom TLS configuration such as CA certs, client certificates, etc.). +6. **FR-1.6** — The bearer token MUST be attached to every outgoing gRPC request as an `authorization: Bearer ` metadata header. +7. **FR-1.7** — The `Client` MUST implement `Clone`, `Send`, and `Sync`. This is required for sharing across `tokio::spawn` tasks in real-world async services. Internally, `Client` uses `tonic::Channel` which is already `Clone + Send + Sync`. +8. **FR-1.8** — The `Client` MUST be usable when wrapped in `Arc` and shared across `tokio::spawn` tasks. Since `Client` is `Clone` (wrapping a `tonic::Channel` which is cheaply cloneable), `Arc` wrapping is not strictly necessary but MUST work correctly. +9. **FR-1.9** — All RPC methods SHOULD accept an optional per-request timeout/deadline. The builder MUST support a `.default_timeout(Duration)` that applies to all RPCs unless overridden per-request. + +### FR-2: PermissionsService + +10. **FR-2.1** — `CheckPermission` — Given a resource (type + id), a permission/relation name, a subject (type + id + optional relation), and an optional caveat context (`HashMap`), return a `PermissionResult` indicating whether the subject has the permission. MUST support all consistency modes (see FR-6). + + > **Important**: SpiceDB returns a 3-state `Permissionship` enum: `HAS_PERMISSION`, `NO_PERMISSION`, `CONDITIONAL`. Returning `bool` would be lossy and a security hazard — a `CONDITIONAL` result silently coerced to `false` could deny legitimate access, and coerced to `true` could grant unauthorized access. The `PermissionResult` enum preserves all three states faithfully. + + A convenience method `.is_allowed() -> Result` MUST be provided on `PermissionResult`. It MUST return `Ok(true)` for `Allowed`, `Ok(false)` for `Denied`, and `Err(Error::ConditionalPermission { missing_fields })` for `Conditional` — forcing the caller to handle the ambiguous case explicitly rather than silently dropping it. + +11. **FR-2.2** — `LookupResources` — Given a resource type, permission, subject, and optional caveat context, stream back all resource IDs the subject can access. Returns a `Stream`. Each item includes the resource ID and its `PermissionResult` (which may be `Conditional` for caveated relationships). +12. **FR-2.3** — `LookupSubjects` — Given a resource, permission, subject type, and optional caveat context, stream back all subjects that have the permission. Returns a `Stream`. +13. **FR-2.4** — `ExpandPermissionTree` — Given a resource and permission, return the full permission tree. MUST return a structured `PermissionTree` type (recursive tree node), not raw proto. +14. **FR-2.5** — `ReadRelationships` — Given a relationship filter, stream back matching relationships. Returns a `Stream`. Each relationship includes its optional `Caveat` if one is attached. +15. **FR-2.6** — `WriteRelationships` — Accept a list of relationship updates (create/touch/delete) with optional preconditions (`Vec`). Relationships MAY include a `Caveat` (caveat name + context). Return a `ZedToken`. +16. **FR-2.7** — `DeleteRelationships` — Given a relationship filter, optional preconditions (`Vec`), and optional consistency, delete matching relationships. Return a `ZedToken`. + + > **Note on consistency for DeleteRelationships**: This is a mutating operation, but SpiceDB accepts a `Consistency` parameter on `DeleteRelationships` to control the snapshot at which the relationship filter is evaluated. The filter determines which relationships to delete; the consistency mode determines which snapshot is used to resolve that filter. The operation then returns a `ZedToken` representing the state after deletion. See the consistency matrix in FR-6 for the full picture. + +### FR-3: SchemaService + +17. **FR-3.1** — `ReadSchema` — Return the current SpiceDB schema as a `String`. Returns a `ZedToken` alongside the schema text. +18. **FR-3.2** — `WriteSchema` — Accept a schema string and apply it. Return a `ZedToken`. + +### FR-4: WatchService + +19. **FR-4.1** — `Watch` — Given optional object types to filter on, return a `Stream>` of relationship update events. MUST handle long-lived streaming connections with the following explicit behavioral contracts: + + - **On server disconnect**: stream yields `Err(Error::Status { code: UNAVAILABLE, .. })` then terminates (`next()` returns `None`). + - **On empty filter list**: watches all relationship types (SpiceDB default behavior). Stream blocks waiting for events; `next()` returns `None` only when the stream terminates. + - **On server error mid-stream**: stream yields `Err` with the gRPC status mapped to the appropriate `Error` variant, then terminates. + - **No auto-reconnect**: Watch does NOT auto-reconnect. This is the caller's responsibility, consistent with NG-6 (no built-in retry/circuit breaker). Callers can use the checkpoint `ZedToken` from the last `WatchEvent` to resume from where they left off. + - **WatchEvent contents**: Each `WatchEvent` includes the list of relationship updates and a checkpoint `ZedToken` for caller-driven resume. + - **On caller drop**: stream is dropped, underlying gRPC stream is cancelled (standard tonic behavior — the `Drop` impl on the tonic `Streaming` handle cancels the RPC). + +### FR-5: ExperimentalService + +> **Note**: All FR-5.x methods are gated behind `#[cfg(feature = "experimental")]`. See Cargo Feature Flags section. + +20. **FR-5.1** — `BulkCheckPermission` — Accept a batch of check requests (each with optional caveat context) and return a `Vec`. Each `CheckResult` contains either a `PermissionResult` or a per-item `Error`. Single round-trip. +21. **FR-5.2** — `BulkImportRelationships` — Accept an `impl Stream` for client-streaming bulk import. Return an import count. +22. **FR-5.3** — `BulkExportRelationships` — Given a filter, stream back all matching relationships for export. + +### FR-6: Consistency Semantics (ZedTokens) + +23. **FR-6.1** — The library MUST model the four SpiceDB consistency modes as a Rust enum: + - `FullyConsistent` — always check at the latest snapshot + - `AtLeastAsFresh(ZedToken)` — at least as fresh as the given token + - `AtExactSnapshot(ZedToken)` — exactly at the given token's snapshot + - `MinimizeLatency` — server picks the fastest available snapshot +24. **FR-6.2** — Methods that accept a `Consistency` parameter and methods that return a `ZedToken` are detailed in the following matrix: + +#### Consistency Matrix + +| Method | Accepts `Consistency`? | Returns `ZedToken`? | Notes | +|---|---|---|---| +| FR-2.1 `CheckPermission` | ✅ Yes | ✅ Yes (in response) | Read path | +| FR-2.2 `LookupResources` | ✅ Yes | ✅ Yes (per item + final) | Streaming read | +| FR-2.3 `LookupSubjects` | ✅ Yes | ✅ Yes (per item + final) | Streaming read | +| FR-2.4 `ExpandPermissionTree` | ✅ Yes | ✅ Yes (in response) | Read path | +| FR-2.5 `ReadRelationships` | ✅ Yes | ✅ Yes (per item) | Streaming read | +| FR-2.6 `WriteRelationships` | ❌ No | ✅ Yes | Mutating — always writes at latest | +| FR-2.7 `DeleteRelationships` | ✅ Yes (for filter eval) | ✅ Yes | Mutating, but filter is evaluated at the specified consistency snapshot; deletion occurs at latest. See FR-2.7 note. | +| FR-3.1 `ReadSchema` | ❌ No | ✅ Yes | Schema reads don't accept consistency | +| FR-3.2 `WriteSchema` | ❌ No | ✅ Yes | Mutating | +| FR-4.1 `Watch` | N/A (uses `after_token`) | ✅ Yes (checkpoint per event) | Watch resumes from a token, not a consistency mode | +| FR-5.1 `BulkCheckPermission` | ✅ Yes | ✅ Yes (in response) | Experimental | +| FR-5.2 `BulkImportRelationships` | ❌ No | ❌ No (returns count) | Experimental, client-streaming | +| FR-5.3 `BulkExportRelationships` | ✅ Yes | ✅ Yes (per item) | Experimental, streaming read | + +25. **FR-6.3** — Every mutating method (FR-2.6, FR-2.7, FR-3.2) MUST return a `ZedToken` that callers can store and pass to subsequent reads. +26. **FR-6.4** — When no consistency is specified on a method that accepts it, the library MUST send no consistency preference to the server. This means SpiceDB will apply its default consistency mode, which is `MinimizeLatency`. This behavior MUST be documented clearly in the crate-level docs and on each method that accepts consistency, so test authors know what to expect. + +### FR-7: Error Handling + +27. **FR-7.1** — The library MUST define a crate-level `Error` enum with the following concrete variants: + + ```rust + #[derive(Debug)] + pub enum Error { + /// Connection-level failures: connection refused, DNS resolution failure, TLS handshake + /// errors, channel closed. + Transport(tonic::transport::Error), + + /// gRPC status errors returned by SpiceDB. Includes the status code, human-readable + /// message, and optionally decoded SpiceDB-specific error details. + Status { + code: tonic::Code, + message: String, + details: Option, + }, + + /// Local validation failures before a request is sent. Examples: empty object_type, + /// empty object_id, empty schema string, empty relationship update list. + InvalidArgument(String), + + /// Protobuf encode/decode failures. Should be rare — indicates a bug or proto mismatch. + Serialization(String), + + /// Returned by PermissionResult::is_allowed() when the result is Conditional. + /// Forces callers to handle the caveated case explicitly. + ConditionalPermission { + missing_fields: Vec, + }, + } + ``` + +28. **FR-7.2** — All public methods MUST return `Result`. +29. **FR-7.3** — The `Error` type MUST implement `std::error::Error`, `Debug`, `Display`, `Send`, `Sync`, and `'static`. +30. **FR-7.4** — The library SHOULD decode SpiceDB-specific error details from gRPC status metadata where available (e.g., `debug_information` from `ErrorReason`). +31. **FR-7.5** — The `Error` type MUST provide an `is_retryable(&self) -> bool` helper method. The following gRPC status codes are considered retryable: `UNAVAILABLE`, `DEADLINE_EXCEEDED`. All other status codes are non-retryable by default. +32. **FR-7.6** — The library MUST map gRPC status codes to semantically meaningful categories. The following mapping table MUST be documented in crate-level error docs: + + | gRPC Status Code | Semantic Meaning | Retryable? | + |---|---|---| + | `UNAUTHENTICATED` | Authentication failure — invalid or missing bearer token | No | + | `PERMISSION_DENIED` | Authorization failure — token valid but insufficient permissions for this operation | No | + | `NOT_FOUND` | Referenced resource or schema not found | No | + | `FAILED_PRECONDITION` | Precondition on a write/delete was violated | No | + | `INVALID_ARGUMENT` | Server rejected the request as malformed | No | + | `ALREADY_EXISTS` | Attempted to create a relationship that already exists (when using `Create` not `Touch`) | No | + | `UNAVAILABLE` | Server temporarily unavailable — safe to retry | Yes | + | `DEADLINE_EXCEEDED` | Request timed out — may be safe to retry | Yes | + + > **Distinguishing authentication from authorization**: `UNAUTHENTICATED` means the caller's identity could not be established (bad token). `PERMISSION_DENIED` means the identity is known but lacks the required SpiceDB service-level permission. These are distinct failure modes and callers may need to handle them differently (e.g., refresh token vs. escalate to admin). + +### FR-8: Type-Safe Domain Model + +33. **FR-8.1** — The library MUST provide high-level Rust types for core domain concepts: `ObjectReference` (type + id), `SubjectReference` (object ref + optional relation), `Relationship`, `RelationshipUpdate`, `RelationshipFilter`, `SubjectFilter`, `Precondition`, `Permission`, `ZedToken`, `PermissionResult`, `PermissionTree`, `WatchEvent`, `CheckResult`, `Caveat`, `ContextValue`, `LookupResourceResult`, `LookupSubjectResult`, `ReadRelationshipResult`, `SpiceDbErrorDetails`. +34. **FR-8.2** — These types MUST NOT be raw protobuf-generated structs. They MUST be idiomatic Rust types with the generated protos as an internal implementation detail. +35. **FR-8.3** — Builder patterns or `From`/`Into` conversions SHOULD be provided for constructing complex request types. +36. **FR-8.4** — `ObjectReference` and `SubjectReference` MUST validate that `object_type` and `object_id` are non-empty at construction time. + +### FR-9: Common Trait Derives + +37. **FR-9.1** — All public **domain/value** types MUST derive `Debug` and `Clone`. The `Error` type is excluded from `Clone` since it wraps `tonic::transport::Error` which is not `Clone`. +38. **FR-9.2** — Equality and hash trait requirements are specified per-type based on field implementability, not as a blanket rule: + - Public value types MUST derive `PartialEq` **unless** the type transitively contains `Error` (which wraps non-comparable transport internals). + - Public value types MUST derive `Eq` and `Hash` **only when all fields support those traits**. + - **`PartialEq + Eq + Hash`**: `ObjectReference`, `SubjectReference`, `SubjectFilter`, `RelationshipFilter`, `Precondition`, `PreconditionOp`, `Operation`, `ZedToken`, `Consistency`, `PermissionResult`, `LookupResourceResult`, `LookupSubjectResult`, `PermissionTree`, `PermissionTreeNode`, `SpiceDbErrorDetails`. + - **`PartialEq` only** (no `Eq`/`Hash` — contains `f64` or `HashMap` transitively): `ContextValue`, `Caveat`, `Relationship`, `RelationshipUpdate`, `ReadRelationshipResult`, `WatchEvent`. + - **No equality/hash traits**: `CheckResult` (contains `Error`). +39. **FR-9.3** — `ZedToken` MUST implement `Serialize` and `Deserialize` (via `serde`) for persistence (e.g., storing in a database or passing between services). This is gated behind the `serde` feature flag. +40. **FR-9.4** — `ZedToken` MUST redact its token value in `Debug` output for security (display as `ZedToken("***")` or similar). Token values may be sensitive and should not appear in application logs. +41. **FR-9.5** — `Error` MUST implement `Debug` and `Display` (via `std::error::Error` — see FR-7.3). + +### FR-10: Boundary Conditions + +42. **FR-10.1** — Passing an empty `Vec` to `write_relationships` MUST return `Err(Error::InvalidArgument("..."))` without making a network call. +43. **FR-10.2** — Passing an empty string to `write_schema` MUST return `Err(Error::InvalidArgument("..."))` without making a network call. +44. **FR-10.3** — Passing an empty filter list to `watch` MUST watch all relationship types (this is SpiceDB's default behavior, not an error). +45. **FR-10.4** — `ZedToken` construction MUST require a non-empty string. Attempting to construct a `ZedToken` from an empty string MUST return `Err(Error::InvalidArgument(...))`. No panicking. (Rationale: consistent with FR-8.4 which uses construction-time validation returning errors.) + +--- + +## Non-Functional Requirements + +| ID | Category | Requirement | +|---|---|---| +| **NFR-1** | **Idiomacy** | Public API follows Rust API guidelines (C-COMMON-TRAITS, C-BUILDER, etc. per [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/)). | +| **NFR-2** | **Async** | All network-calling methods are `async`. No blocking calls on async threads. | +| **NFR-3** | **Runtime** | Requires `tokio` runtime. No runtime-agnostic abstraction layer (see Non-Goals). | +| **NFR-4** | **Compilation** | Compiles on latest stable Rust. No nightly-only features. | +| **NFR-5** | **Dependencies** | Minimal dependency tree. Core deps: `tonic`, `prost`, `prost-types`, `tokio`, `tower` (for interceptors). Optional deps: `serde` (behind feature flag), `tracing` (for diagnostics). No further large frameworks. | +| **NFR-6** | **Documentation** | Every public type, method, and module has `///` doc comments. Crate-level docs include a getting-started example. Error docs include gRPC status code mapping table. | +| **NFR-7** | **Testing** | Unit tests for type construction/validation, boundary conditions, error variant matching. Integration tests against a real SpiceDB instance (via `testcontainers` or similar). CI runs both. | +| **NFR-8** | **Streaming** | Server-streaming RPCs return `impl Stream>` (via `tokio-stream` or `futures::Stream`). Streaming methods MUST NOT return boxed trait objects — use `impl Stream` or named stream types. | +| **NFR-9** | **Performance** | Channel reuse: no per-request connection overhead.

Feature-gating signals instability to consumers. | +| `watch` | No | WatchService (FR-4.x) | Requires long-lived connections with different operational characteristics. Separated so consumers who don't need it don't pull in watch-related code. | +| `serde` | No | `Serialize`/`Deserialize` derives on `ZedToken` and other domain types | Optional dependency — many consumers won't need persistence. | +| `tls-rustls` | No | Use `rustls` as TLS backend (via tonic's `tls-rustls` feature) | Pure-Rust TLS — no system OpenSSL dependency. | +| `tls-native` | No | Use native TLS (via tonic's `tls-native` feature) | Uses system OpenSSL/Schannel/SecureTransport. | + +> **Note**: If neither `tls-rustls` nor `tls-native` is enabled, TLS is handled by tonic's default behavior (which typically requires one of these features for `https://` connections). The crate documentation MUST clearly state this. + +--- + +## Non-Goals + +The following are explicitly **out of scope** for v1: + +| # | Non-Goal | Rationale | +|---|---|---| +| NG-1 | CLI binary | This is a library crate. CLI tooling is a separate concern. | +| NG-2 | Schema DSL parser/compiler | Schema strings are passed through as-is. Parsing the Zanzibar-style DSL is out of scope. | +| NG-3 | Admin / metrics endpoints | SpiceDB admin APIs (health, metrics, dispatch) are not part of the core authorization API. | +| NG-4 | Non-tokio runtime support | Tonic requires tokio. Abstract runtime support adds complexity for minimal benefit. | +| NG-5 | Caching layer | Permission caching is application-specific. The library should be a thin, faithful client. | +| NG-6 | Retry / circuit breaker middleware | Users can compose these via `tower` layers on the channel. Not built in for v1. The `Error::is_retryable()` helper assists callers in building their own retry logic. | +| NG-7 | mTLS support (stretch goal) | Acknowledged as desirable, but deferred as a first-class API. Bearer token auth covers the primary use case. mTLS is achievable today by passing a custom `tonic::Channel` via FR-1.5. | +| NG-8 | Auto-reconnect for Watch | Watch streams terminate on error. The caller is responsible for reconnection logic using the checkpoint `ZedToken` from the last `WatchEvent`. This is consistent with NG-6. | + +--- + +## Open Questions + +| # | Question | Impact | Owner | +|---|---|---|---| +| OQ-3 | Should the crate be published to crates.io or remain internal-only initially? | Affects naming, documentation, and versioning rigor. | Maintainer | +| OQ-4 | What is the minimum supported Rust version (MSRV) policy? Latest stable? N-2? | Affects dependency choices and CI matrix. | Maintainer | +| OQ-7 | What crate name? `prescience`, `spicedb`, `spicedb-client`, `authzed`? | Affects discoverability and potential trademark concerns. | Maintainer | + +--- + +## Risks & Dependencies + +| # | Risk | Likelihood | Impact | Mitigation | +|---|---|---|---|---| +| R-1 | **SpiceDB API breaking changes** — proto definitions change in incompatible ways | Low (v1 API is stable) | High — breaks compiled client | Pin to a specific proto tag; test against multiple SpiceDB versions in CI. | +| R-2 | **Tonic major version bump** — tonic 0.x is pre-1.0 and may have breaking changes | Medium | Medium — requires code changes | Pin tonic version range; monitor releases. | +| R-3 | **Protobuf codegen drift** — generated code diverges from what SpiceDB actually accepts | Low | High — runtime failures | Integration tests against a real SpiceDB container in CI. | +| R-4 | **Streaming complexity** — long-lived Watch streams may have subtle error handling bugs | Medium | Medium — unreliable watch | Explicit streaming behavioral contracts (see FR-4.1 and streaming behavior table). Document limitations clearly. | +| R-5 | **Naming collision** — crate name conflicts with existing crates.io packages | Low | Low — rename before publish | Check crates.io availability early. | +| R-6 | **Caveat complexity** — `ContextValue` mapping to/from `prost_types::Value` may have edge cases (e.g., NaN, infinity, deeply nested structs) | Medium | Low — runtime surprises | Thorough unit tests for ContextValue round-tripping. Document known limitations. | + +### External Dependencies + +| Dependency | Version (indicative) | Purpose | +|---|---|---| +| `tonic` | 0.12+ | gRPC client framework | +| `prost` | 0.13+ | Protobuf serialization | +| `prost-types` | 0.13+ | Well-known protobuf types (Struct, Value for caveat context) | +| `tokio` | 1.x | Async runtime | +| `tower` | 0.4+ / 0.5+ | Service middleware (bearer token interceptor) | +| `tonic-build` | 0.12+ (build-dep) | Protobuf code generation | +| `authzed/api` | latest tagged release | Protobuf source definitions (pinned to tag, not `main`) | +| `serde` | 1.x (optional) | Serialization for ZedToken and domain types | +| `tracing` | 0.1.x | Diagnostic logging (e.g., insecure connection warnings) | + +--- + +## Decisions Made + +| # | Decision | Rationale | +|---|---|---| +| D-1 | **Use `tonic` for gRPC transport** | De facto standard Rust gRPC library. Mature, actively maintained, built on tokio + hyper + tower. | +| D-2 | **Generate types from official `authzed/api` protos** | Single source of truth. Avoids manual type definitions falling out of sync. | +| D-3 | **Wrap generated protos in idiomatic Rust types** | Raw proto types have `Option` everywhere and stringly-typed fields. Wrapping provides validation, ergonomics, and a stable public API decoupled from proto layout. | +| D-4 | **Require `tokio` runtime** | Tonic requires tokio. Supporting multiple runtimes adds complexity with no current demand. | +| D-5 | **Bearer token auth, not mTLS, for v1** | Covers the vast majority of SpiceDB deployments. mTLS can be layered in by passing a custom channel (FR-1.5). | +| D-6 | **Library crate only** | Keeps scope focused. CLI and other binaries are separate concerns. | +| D-7 | **Custom error type, not `anyhow`/`eyre`** | Library crates should provide structured errors that callers can match on. Concrete enum variants enable exhaustive matching and testable error assertions. | +| D-8 | **Streaming methods return `impl Stream`** | Consistent async Rust idiom. Not boxed trait objects — `impl Stream` for zero-cost. Callers can use `StreamExt` combinators or `while let` loops. | +| D-9 | **Pin to latest tagged release of `authzed/api` (not `main`)** | Resolved from OQ-1. Tagged releases are stable and versioned. Tracking `main` risks ingesting breaking or incomplete proto changes. Pin to a specific tag (e.g., `v1.35.0`) and update deliberately. | +| D-10 | **Use `build.rs` codegen (don't commit generated code)** | Resolved from OQ-2. Standard Rust approach. Avoids stale generated code in the repo. Consumers need `protoc` installed (documented in README) or we vendor the proto files and use `prost-build` which doesn't require `protoc`. | +| D-11 | **Feature-gate ExperimentalService behind `#[cfg(feature = "experimental")]`** | Resolved from OQ-5. These APIs may change without notice in SpiceDB. Feature-gating clearly signals instability and prevents accidental reliance. | +| D-12 | **Caveats are IN SCOPE for v1 (read/check path + write path)** | Resolved from OQ-6. Caveated relationships are a core SpiceDB feature. Omitting caveat support would make the client unable to correctly interpret `CONDITIONAL` permission results — a security hazard. The `PermissionResult` enum faithfully represents all three states. | +| D-13 | **`CheckPermission` returns `PermissionResult` enum, not `bool`** | SpiceDB's 3-state Permissionship (HAS_PERMISSION / NO_PERMISSION / CONDITIONAL) cannot be faithfully represented as a boolean. Returning `bool` is lossy and a security hazard. A convenience `.is_allowed()` method is provided but returns `Result` to force handling of the CONDITIONAL case. | +| D-14 | **TLS determined by URI scheme with explicit override** | `https://` = TLS, `http://` = plaintext. Builder `.tls(bool)` overrides. Non-loopback `http://` requires `.insecure(true)`. Follows principle of secure-by-default with explicit opt-out. | +| D-15 | **No auto-reconnect for streaming** | Consistent with NG-6 (no built-in retry). Callers manage reconnection using checkpoint ZedTokens. This keeps the library thin and avoids opinionated retry policies. | + +--- + +## References + +- [SpiceDB Documentation](https://authzed.com/docs) +- [SpiceDB Caveats Documentation](https://authzed.com/docs/spicedb/concepts/caveats) +- [authzed/api Protobuf Definitions](https://github.com/authzed/api) +- [lunaetco/spicedb-client (community Rust client)](https://github.com/lunaetco/spicedb-client) +- [Google Zanzibar Paper](https://research.google/pubs/pub48190/) +- [Tonic gRPC Framework](https://github.com/hyperium/tonic) +- [Rust API Guidelines](https://rust-lang.github.io/api-guidelines/) diff --git a/src/lib.rs b/src/lib.rs new file mode 100644 index 0000000..b18e9c9 --- /dev/null +++ b/src/lib.rs @@ -0,0 +1 @@ +//!

Fix 'Idiomacy' → 'Idiomaticity' typo in spec (NFR-1) 2. Add empty vec validation in write_relationships before network call (FR-10.1) 3. Fix loopback check bypass — parse URI properly instead of substring matching, preventing hosts like 'localhost.evil.com' from being treated as loopback 4. Add .consistency() to DeleteRelationshipsRequest — removed after checking proto (DeleteRelationships doesn't accept consistency); updated spec to match proto 5. Batch bulk import with chunks of 128 instead of 1-per-message, using async_stream for proper streaming batches 6. Remove .tls(bool) from spec — TLS is by URI scheme only; advanced TLS via Client::from_channel() 7. Validate SubjectReference::new rejects Some("") — use None instead 8. Validate exclusion tree node requires exactly 2 children (not >= 2) 9. Add integration test for write_relationships(vec![]) rejection 10. Add unit test for SubjectReference empty relation rejection 38 tests passing (29 unit + 9 doc), zero clippy warnings. --- Cargo.lock | 1 + Cargo.toml | 1 + specs/requirements/001-rust-spicedb-client.md | 12 ++++----- src/client/builder.rs | 18 ++++++++++--- src/client/experimental.rs | 27 ++++++++++++++----- src/client/permissions.rs | 6 +++++ src/types/permission.rs | 20 +++++++------- src/types/reference.rs | 20 ++++++++++++-- tests/integration.rs | 7 +++++ 9 files changed, 82 insertions(+), 30 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 1269c4d..64da748 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -576,6 +576,7 @@ version = "0.1.0" dependencies = [ "async-stream", "futures-core", + "http", "prost", "prost-types", "serde", diff --git a/Cargo.toml b/Cargo.toml index f9d0f3c..c963a51 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -19,6 +19,7 @@ tls-native = ["tonic/tls"] [dependencies] async-stream = "0.3" futures-core = "0.3" +http = "1" prost = "0.13" prost-types = "0.13" serde = { version = "1", features = ["derive"], optional = true } diff --git a/specs/requirements/001-rust-spicedb-client.md b/specs/requirements/001-rust-spicedb-client.md index 4dacb7d..d92d2dc 100644 --- a/specs/requirements/001-rust-spicedb-client.md +++ b/specs/requirements/001-rust-spicedb-client.md @@ -30,7 +30,7 @@ No UI actors.
