/**
 * Decorator that marks a class as a [provider](https://docs.nestjs.com/providers).
 * Providers can be injected into other classes via constructor parameter injection
 * using Nest's built-in [Dependency Injection (DI)](https://docs.nestjs.com/providers#dependency-injection)
 * system.
 *
 * When injecting a provider, it must be visible within the module scope (loosely
 * speaking, the containing module) of the class it is being injected into. This
 * can be done by:
 *
 * - defining the provider in the same module scope
 * - exporting the provider from one module scope and importing that module into the
 *   module scope of the class being injected into
 * - exporting the provider from a module that is marked as global using the
 *   `@Global()` decorator
 *
 * Providers can also be defined in a more explicit and imperative form using
 * various [custom provider](https://docs.nestjs.com/fundamentals/custom-providers) techniques that expose
 * more capabilities of the DI system.
