使用
// 声明你的接口.
// 文件📃 types.ts
import { Token, TokenType } from "inversify-token";
import { Warrior, Weapon, ThrowableWeapon } from "./interfaces"
const WarriorToken = new Token<Warrior>(Symbol.for("Warrior"));
type WarriorToken = TokenType<typeof WarriorToken>;
const WeaponToken = new Token<Weapon>(Symbol.for("Weapon"));
type WeaponToken = TokenType<typeof WeaponToken>;
const ThrowableWeaponToken = new Token<ThrowableWeapon>(Symbol.for("ThrowableWeapon"));
type ThrowableWeaponToken = TokenType<typeof ThrowableWeaponToken>;
export {
WarriorToken as Warrior,
WeaponToken as Weapon,
ThrowableWeaponToken as ThrowableWeapon,
