Type Alias RPCValidators<API>

RPCValidators: {
    [K in keyof API]?: API[K] extends (...args: infer A) => infer R
        ? MethodValidators<A, R>
        : API[K] extends Record<string, unknown> ? RPCValidators<API[K]> : never
}

Recursively map an API type to its validator shape.

Given an API like:

type API = {
  add(a: number, b: number): Promise<number>
  math: { multiply(a: number, b: number): Promise<number> }
}

This produces:

{
  add?: { input?: StandardSchemaV1<[number, number]>, output?: StandardSchemaV1<number> }
  math?: { multiply?: { input?: ..., output?: ... } }
}

Functions → MethodValidators<Parameters, ReturnType>
Nested objects → recurse into RPCValidators<NestedAPI>
Primitive properties / constructors → excluded (never)

Every key is optional at every level, so you only validate what you want.
