Function: func()

func<S>(schema?, message?): FunctionValidator<ExtractInput<S>, ExtractOutput<S>> & StandardSchemaV1<InferFunction<ExtractInput<S>, ExtractOutput<S>>, InferFunction<ExtractInput<S>, ExtractOutput<S>>>

Defined in: Validate/function/core.ts:100

Creates a function validator. When invoked the validator only checks that the value is callable; use .implement() on the returned validator to obtain a runtime-checked wrapper that asserts the schema for each call.

Type Parameters

S

S extends FunctionSchema = FunctionSchema

Function schema type, captured for input/output inference

Parameters

schema?

S

Function schema definition

message?

string

Custom error message for type validation

Returns

FunctionValidator<ExtractInput<S>, ExtractOutput<S>> & StandardSchemaV1<InferFunction<ExtractInput<S>, ExtractOutput<S>>, InferFunction<ExtractInput<S>, ExtractOutput<S>>>

• Validator augmented with implement()
