Trait UseState 

pub trait UseState: Sealed {
    // Required method
    fn use_state<T, F>(&mut self, init: F) -> State<T>
       where F: FnOnce() -> T,
             T: Unpin + Send + Sync + 'static;
}

Required Methods

fn use_state<T, F>(&mut self, init: F) -> State<T>

where F: FnOnce() -> T, T: Unpin + Send + Sync + 'static,

为 Hooks 提供 use_state 方法，创建响应式状态。

• init：状态初始化闭包。
• 返回 State<T>。

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.
