A dependency injection lib for Reactant

import { ServiceIdentifierOrFunc } from '../interfaces';
/**
 * ## Description
 *
 * You can use `@inject()` to perform the required dependency injection module to decorate in the constructor of an injectable class.
 *
 * If the default is a dependency injection of the class itself as a type, e.g. `@inject(Foo) foo: Foo`, then it is exactly the same as `foo: Foo`.
 *
 * ## Example
 *
 * ```ts
 * @injectable()
 * class Bar {
 *   getValue() {
 *     return 'bar';
 *   }
 * }
 *
 * @injectable()
 * class Foo {
 *   getValue() {
 *     return 'foo';
 *   }
 * }
 *
 * @injectable()
 * class FooBar {
 *   constructor(@inject() public bar: Bar, @inject('foo') public foo: Foo) {}
 * }
 *
 * const fooBar = testBed({
 *   modules: [
 *    Bar,
 *    { provide: 'foo', useClass: Foo },
 *   ],
 *   main: FooBar,
 * });
 *
 * expect(fooBar.instance.foo.getValue()).toBe('foo');
 * ```
