在这里,Encoder 编码是指将用户自定义类型转换成 BytesMut 类型,写到 TcpStream 中,Decoder 解码指将读到的字节数据序列化为 Rust 的结构体。 implEncoder<Message>forPisaProxy{typeError= ProtocolError;fnencode(&mutself, item: Message, dst: &mutBytesMut)->Result<(),Self::Error> { ...
dst.extend(item.as_bytes()); Ok(()) } } impl Decoder for PisaProxy { type Item = Message; type Error = ProtocolError; fn decode(&mut self, src: &mut BytesMut) -> Result<Option<Self::Item>, Self::Error> { if src.is_empty() { ...
TC classifier(译:TC分类器) – 能被附加到 qdisc (“queuing discipline” in Linux networking) 的出口和入口,用于检查网络接口和执行某些操作比如 accepting(接受), dropping(释放), redirecting(重定向), sending them to the queue again(再次发送到队列)等。
