pub trait Inject {
    fn inject(container: &Container<'_>) -> Self;
}
Expand description

A trait for constructing a type getting the dependencies from a Container.

Example

use std::sync::Mutex;
use dilib::{Singleton, Inject, Container};

struct Greeter {
   message: String,
   total_greets: Singleton<Mutex<usize>>
}

impl Greeter {
    fn greet(&self) {
        println!("{}", self.message);
        *self.total_greets.lock().unwrap() += 1;
    }
}

impl Inject for Greeter {
    fn inject(container: &Container) -> Self{
        let message = container.get_scoped_with_name::<String>("es_msg").unwrap();
        let total_greets = container.get_singleton_with_name::<Mutex<usize>>("count").unwrap();
        Greeter { message, total_greets }
    }
}
