Inline generated serializers to remove anonymous functions

This PR removes the generation of per-schema anonymous serializer functions and fully inlines all serialization logic into a single main function.

Eg. this schema:

{
  type: 'object',
  properties: {
    firstName: { type: 'string' },
    lastName: { type: 'string' },
    age: { type: 'integer' },
    address: {
      type: 'object',
      properties: {
        street: { type: 'string' },
        city: { type: 'string' },
        zip: { type: 'string' }
      }
    },
    hobbies: {
      type: 'array',
      items: { type: 'string' }
    }
  }
}

Each nested schema (address, hobbies, root) generated its own anonymous serializer function.
The root serializer (anonymous0) delegated work via function calls (anonymous1, anonymous2).
Serialization flow = function calls + stack frames

Actually generate this output code:

This avoids:

Call overhead
Stack frame creation
De-optimizations in tight loops
This is especially relevant for high-throughput serialization.

Better JIT optimization opportunities

Inlining allows the JS engine to:

Perform constant folding across nested scopes
Keep json and addComma in registers
Avoid polymorphic call sites

With separate functions, V8 often cannot inline aggressively due to:

Closure boundaries
Indirect references
Different argument shapes

Reduced memory pressure:

No extra function objects allocated
No closures capturing shared constants
Fewer references held alive by the serializer

If this PR gets approved I would like to move the methods asString, asNumber, asBoolean, asDateTime, asDate, asTime, asUnsafeString inline as well ( see #813 ), eg.:

function inlineAsInteger (options, input) {
  let roundingFn = 'Math.trunc'
  if (options && options.rounding) {
    switch (options.rounding) {
      case 'floor':
        roundingFn = 'Math.floor'
        break
      case 'ceil':
        roundingFn = 'Math.ceil'
        break
      case 'round':
        roundingFn = 'Math.round'
        break
    }
  }

  return `
    if (Number.isInteger(${input})) {
      json += ${input}
    } else if (typeof ${input} === 'bigint') {
      json += ${input}.toString()
    } else {
      const integer = ${roundingFn}(${input})
      if (integer === Infinity || integer === -Infinity || integer !== integer) {
        throw new Error('The value "' + ${input} + '" cannot be converted to an integer.')
      }
      json += integer
    }
  `
}

Wow, good work!

Eomm · 2026-01-17T09:42:00Z

Should we update the readme bench too?

Should we update the readme bench too?

Also see #816 for better output format!
