Trait Inject

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

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 }
    }
}

Required Methods

fn inject(container: &Container<'_>) -> Self

Constructs this type using the Container.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
