🤖 The ultimate library you need for composable type-level programming in TypeScript, powered by HKT.

import type { None, Option } from ".";
import type { Args, Fn } from "../HKT";

declare module "../typeclass/HKT" {
  interface HKTRegistry {
    Option: RegisterHKT<Option$$HKT$$Builder, Option$$HKT$$Extractor>;
  }
}

export interface Option$$HKT$$Builder extends Fn<[unknown], Option<unknown>> {
  def: ([x]: Args<this>) => Option<typeof x>;
}

export interface Option$$HKT$$Extractor extends Fn<[Option<unknown>], unknown> {
  def: ([o]: Args<this>) => typeof o extends None ? never
  : typeof o extends Option<infer T> ? T
  : never;
}
