Struct HandlerWrapper 

pub struct HandlerWrapper<F> { /* private fields */ }

处理器包装结构体 包含 请求类型: Option 请求方法: Handler 其中请求类型可为空，用来定义中间件 请求方法不可为空，用来定义处理器 处理器为返回值为 Into + From的异步函数或者闭包函数

Implementations

impl<F, T, Fut> HandlerWrapper<F>

where Fut: Future<Output = Result<T>> + Send + 'static, F: Fn(Request) -> Fut, T: Into<Response>,

pub fn new(handler: F) -> Self

pub async fn handle(&self, req: Request) -> Result<Response>

pub fn arc(self) -> Arc<Self>

Trait Implementations

impl<F, T, Fut> Handler for HandlerWrapper<F>

where Fut: Future<Output = Result<T>> + Send + 'static, F: Fn(Request) -> Fut + Send + Sync + 'static, T: Into<Response>,

为HandlerWrapper实现Handler

fn call<'life0, 'async_trait>( &'life0 self, req: Request, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,
