IoC service container and dependency injection for the rok ecosystem.

Provides a runtime type-map DI container, #[derive(Injectable)] for auto-wiring structs, and Axum extractors Inject<T> and Bound<T>.

Quick start

use std::sync::Arc;
use axum::{routing::get, Extension, Router};
use rok_container::{Container, Inject};

async fn hello(Inject(svc): Inject<GreetService>) -> String {
    svc.greet()
}

let container = Arc::new(Container::new());
container.singleton(GreetService::new());

let app = Router::new()
    .route("/hello", get(hello))
    .layer(Extension(Arc::clone(&container)));
