Trait Implementations§

Source§

impl<F, Fut> RequestHandler for FnHandler<F>
where F: Fn(u64, Bytes) -> Fut + Send + Sync + 'static, Fut: Future<Output = Option<Vec<u8>>> + Send + 'static,

Source§

fn handle<'life0, 'life1, 'async_trait>( &'life0 self, conn_id: u64, request: &'life1 IncomingRequest, ) -> Pin<Box<dyn Future<Output = Option<Vec<u8>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

处理请求，返回响应 body（protobuf 编码后的字节） 返回 None 表示不产生响应（例如异步响应场景）
