有限容量(Bounded)的channel内部实现就是一个简单的Mutex<VecDeque<T>>,性能比Go语言的channel还差 有Sender(=Unbouded)和SyncSender(=Bounded)的区分,用起来不统一。 crossbeam中加强版的channel 首先,无论容量是否有限,Sender类型统一成一种,这样用起来就很方便。其次对有限容量的channel进行了重写(...
use crossbeam_channel::bounded;use std::thread;use std::time::Duration;fn main() { //创建一个无限制容量的通道 let (s,r) = bounded(1); //向通道发送一条消息 s.send("one").unwrap(); thread::spawn(move || { println!("等待发送"); s.send("two").unwrap();...
Auto merge of #17842 - mo8it:crossbeam-channel, r=<try> Browse files Optimize the usage of channel senders Used `Sender` directly instead of a boxed closure. There is no need to use the boxed closure. This also allows the caller to decide to do something other than `unwrap` (not...

context中文直译是语境。在程序设计中,专业的说法是上下文,可以理解为用来记录外部环境参数的模块。下面是crossbeam_channel包context组件给出的文档说明及源码。 Context in crossbeam_channel::context - Rustdoc.servo.org/crossbeam_channel/context/struct.Context.html# ...
