科瓦尔

一个非常简单的 Rust IOC 框架。运行时，无宏。您可以绑定类型到类型，以及容器到容器，以抽象实现选择。

用法

use koval::{Container, Injectable, InjectionError};

pub trait FooServiceTrait: Send + Sync {
    fn foo_function(&self) -> bool;
}

pub type IFooService = Arc<dyn FooServiceTrait>;

pub struct FooServiceImpl {}

impl FooServiceTrait for FooServiceImpl {
    fn foo_function(&self) -> bool {
        true
    }
}

impl Injectable<IFooService> for FooServiceImpl {
    fn resolve_injectable(_: &Container) -> Result<IFooService, InjectionError> {
        Ok(Arc::new(FooServiceImpl {}))
    }
}

fn main()  {
    let container = Container::new()
        .bind_singleton::<IFooService, FooServiceImpl>()
        .build()
        .expect("Container failed to build");
    
    let foo_instance = container.resolve::<IFooService>().unwrap();

    assert_eq!(foo_instance.foo_function(), true);
}
