Expand description

Represents a module.

§Example

use rudi::{
    modules, providers, singleton, transient, Context, DynProvider, Module, ResolveModule,
};

struct Module1;

impl Module for Module1 {
    fn eager_create() -> bool {
        true
    }

    fn providers() -> Vec<DynProvider> {
        providers![singleton(|_| "Hello").name("1")]
    }
}

struct Module2;

impl Module for Module2 {
    fn submodules() -> Option<Vec<ResolveModule>> {
        Some(modules![Module1])
    }

    fn providers() -> Vec<DynProvider> {
        providers![transient(|_| "World").name("2")]
    }
}

let mut cx = Context::create(modules![Module2]);
let mut a = cx.resolve_by_type::<&'static str>();
a.sort();
assert!(format!("{:?}", a) == *r#"["Hello", "World"]"#);
