Derive macros for dependency-injector

This crate provides the #[derive(Inject)] macro for automatic dependency injection at compile time.

Example

use dependency_injector::{Container, Inject};
use std::sync::Arc;

#[derive(Clone)]
struct Database {
    url: String,
}

#[derive(Clone)]
struct Cache {
    size: usize,
}

#[derive(Inject)]
struct UserService {
    #[inject]
    db: Arc<Database>,
    #[inject]
    cache: Arc<Cache>,
    // Non-injected fields use Default
    request_count: u64,
}

let container = Container::new();
container.singleton(Database { url: "postgres://localhost".into() });
container.singleton(Cache { size: 1024 });

let service = UserService::from_container(&container).unwrap();
