Trait UseEffect 

pub trait UseEffect: Sealed {
    // Required methods
    fn use_effect<F, D>(&mut self, f: F, deps: D)
       where F: FnOnce(),
             D: Hash;
    fn use_async_effect<F, D>(&mut self, f: F, deps: D)
       where F: Future<Output = ()> + Send + 'static,
             D: Hash;
}

Required Methods

fn use_effect<F, D>(&mut self, f: F, deps: D)

where F: FnOnce(), D: Hash,

注册同步副作用，依赖变化时自动执行，适合监听状态变化、同步校验等。

fn use_async_effect<F, D>(&mut self, f: F, deps: D)

where F: Future<Output = ()> + Send + 'static, D: Hash,

注册异步副作用，依赖变化时自动执行，适合异步校验、异步请求等。

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
