如果类型T实现了Send,那么Mutex<T>会自动实现Send和Sync。它的使用方法也比较简单,在使用之前需要通过lock或try_lock方法来获取锁,然后再进行操作。那么现在我们就可以对前面的代码进行修复了。 代码语言:txt 复制 use std::thread; use std::sync::{Arc, Mutex}; fn main() { let mut s = Arc::new(Mute...

I have improved it and will try again. Now it directly parses [no_std] in .rs to determine whether it is no_std. That's it Sign up for freeto join this conversation on GitHub. Already have an account?Sign in to comment
在开始实现一个单线程web服务器之前,我们来快速的了解下里面涉及到的协议。 对这一块早已熟悉到爆的大佬可以绕过了,以下内容仅提供给我这样的小白。 HTTP是Hypertext Transfer Protocol的缩写也就是超文本传输协议,而TCP则是Transmission Control Protocol即传输控制协议。

join("include")] 若没有指定编译模式则会首先去找环境变量 FFMPEG_DIR 它指定了 FFMPEG 的位置,在这一模式下会去链接预编译的库,通过 rustc-link-search instruction添加预编译库文件夹到库索引。 Line 687~705 } else if let Some(paths) = try_vcpkg(statik) { // vcpkg doesn't detect the "...
这个设计仅仅是多种改善Web服务器吞吐量的方法之一。其他可供探索的方法有fork/join模型和单线程异步I/O模型。如果你对这个主题感兴趣,则可以阅读更多关于其他解决方案的内容并尝试用Rust实现他们;对于一个像Rust这样的底层语言,所有这些方法都是可能的。
