Expand description

Extension trait for containers to auto-register services.

Required Methods§

Source

fn provide<T: Service>(&self)

Register a service using its Service implementation.

The service will be created lazily on first access, with dependencies resolved from the container.

§Panics

The created factory will panic at runtime if dependencies are missing. For compile-time safety, use the typed builder API.

§Example

use dependency_injector::{Container, verified::{Service, ServiceProvider}};

#[derive(Clone)]
struct MyService;

impl Service for MyService {
    type Dependencies = ();
    fn create(_: ()) -> Self { MyService }
}

let container = Container::new();
container.provide::<MyService>();

let service = container.get::<MyService>().unwrap();
