A simple dependency injection library for Rust
Silhouette implements a simple service container in Rust for dependency injection. It not only provides a Container struct for local usage, but also a static interface (under facade::Container) for easily managing dependencies throughout your application. It's heavily inspired by Laravel's Service Container.
use silhouette::facade::Container;
struct DBPool {}
struct DBConnection {}
// will always use the same pool
Container::singleton(&|_| DBPool::new())?;
// will resolve a new connection each time
Container::bind(&|container| -> DBConnection {
let shared_pool = container.resolve::<DBPool>().unwrap();
shared_pool.get_conn()
})?;
// somewhere else in your app...
let connection: DBConnection = Container::resolve()?;Refer to the documentation on docs.rs for detailed usage instructions.
