StateMatchboxFactory

StateMatchboxFactory<Specs> = { [T in string & keyof Specs]: CreateState<Specs, T> }

Defined in: state-types.ts:48

Utility type for

1. extracting the returned state types from a keyed state factory.
2. extracting the returned payloads from DataSpecs This is a type-level helper for state machine construction: given a tagged type spec (mapping state keys to factory functions or values), States<Specs> produces an object type where each key maps to its corresponding state creator function.

Use this to generate a set of state constructors for a state machine, ensuring type safety and consistency.

Example:

type MySpecs = {
  Idle: () => { ready: boolean };
  Active: (user: string) => { user: string };
};

type MyStates = StateMatchboxFactory<MySpecs>;
// MyStates = {
//   Idle: () => StateMatchbox<'Idle', MySpecs>;
//   Active: (user: string) => StateMatchbox<'Active', MySpecs>;
// }
