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,

创建响应式状态，适合计数器、输入框等本地状态。
