@voyd-lang/package-adapter

Defines the host-language descriptor used to implement Voyd external package interfaces. It is deliberately independent of VX, the compiler, and the host runtime.

Package authors normally generate a typed defineAdapter helper:

voyd generate adapter ./src --out ./generated

import { defineAdapter } from "./generated/voyd-adapter.js";

export default defineAdapter({
  "example:text/format@1": {
    format(value) {
      return value.trim();
    },
  },
});

The lower-level defineVoydPackageAdapter(contract, implementation) API checks the ABI version and requires an exact implementation for every declared sync or async function. It returns a deeply frozen descriptor and performs no global registration or Wasm instantiation.
