Type Parameters

Type Parameter	Default type
`_TInput` extends `Record`<`string`, `any`>	`Record`<`string`, `any`>
`_TOutput` extends `Record`<`string`, `any`>	`Record`<`string`, `any`>

Constructors

Constructor

new AxSignature<_TInput, _TOutput>(signature?: Readonly<
  | string
  | AxSignature<Record<string, any>, Record<string, any>>
| AxSignatureConfig>): AxSignature<_TInput, _TOutput>;

Defined in: https://github.com/ax-llm/ax/blob/be56d0cb4027af0a3a23d397cd01a57261e362d4/src/ax/dsp/sig.ts#L583

Deprecated

Use AxSignature.create() for better type safety instead of the constructor. This constructor will be removed in v15.0.0.

Migration timeline:

v13.0.24+: Deprecation warnings (current)
v14.0.0: Runtime console warnings
v15.0.0: Complete removal

Example

// Instead of: new AxSignature('userInput:string -> responseText:string')
// Use: AxSignature.create('userInput:string -> responseText:string')
