Dependency Injection in Axum

Consider the following Person structure which can be composed into a web application:

use axum::{routing::get, Router};
use di::{injectable, Injectable, ServiceCollection};
use di_axum::{prelude::*, Inject};
use tokio::net::TcpListener;

#[injectable]
struct Person;

impl Person {
    fn speak(&self) -> &str {
        "Hello world!"
    }
}

async fn say_hello(Inject(person): Inject<Person>) -> String {
    person.speak().to_owned()
}

#[tokio::main]
async fn main() {
    let provider = ServiceCollection::new()
        .add(Person::scoped())
        .build_provider()
        .unwrap();

    let app = Router::new()
        .route("/hello", get(say_hello))
        .with_provider(provider);

    let listener = TcpListener::bind("127.0.0.1:5000").await.unwrap();

    println!("Now listening on: {}", listener.local_addr().unwrap());

    axum::serve(listener, app).await.unwrap();
}
