oneshot通道的创建方式是使用oneshot::channel()方法: pubfnchannel<T>() -> (Sender<T>, Receiver<T>) 它返回该通道的写端sender和读端receiver,其中泛型T表示的是读写两端所传递的消息类型。 例如,创建一个可发送i32数据的一次性通道: let(tx, rx) = oneshot::channel::<i32>(); ...

我是否需要在mpsc频道上呼叫close,即使我同时丢弃发件人和接收器? 、 请考虑以下示例: use tokio::sync::mpsc; #[tokio::main] async fn main() { let (mut sender, receiver) = mpsc::channel::(32); sender.send(42).await.unwrap(); std::mem::drop(sender); std::mem::drop(receiver); } ...
