Autowired

Rust dependency injection project

Usage

Just derive your struct with the marco Component, you can use the singleton component everywhere.

#[derive(Default, Component)]
struct Bar {
    name: String,
    age: u32,
}

fn main() {
    // create `bar` via Default::default
    let bar: Autowired<Bar> = Autowired::new();

    assert_eq!(String::default(), bar.name);
    assert_eq!(u32::default(), bar.age);
}

Define custom component initialization logic

#[derive(Default)]
struct Foo {
    value: String,
}

impl Component for Foo {
    type Error = ();

    fn new_instance() -> Result<Arc<Self>, Self::Error> {
        Ok(Arc::new(Foo {
            value: TEST_STRING.to_string(),
        }))
    }
}

fn main() {
    // create `foo` via new_instance
    let foo = Autowired::<Foo>::new();

    assert_eq!("TEST_STRING", foo.value);
}
