先检查 L 是不是 Ready,如果 Ready ,再检查 R 的 Output 是不是有值(并没有 Poll L)。如果是,则把 L 和 R 的 Output 组合成一个 tuple 作为 Join 之后的 Output,然后返回 Poll::Ready 状态 TryJoin 和 Join 类似。先检查 L 是不是 Ready,然后检查 L 的 Output 是不是有错误,如果有错误,就返回E...
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。
rust-analyzer for Vim/Neovim, works as an extension with coc.nvim. Latest version: 0.81.0, last published: 14 days ago. Start using coc-rust-analyzer in your project by running `npm i coc-rust-analyzer`. There are no other projects in the npm registry us
However, the bug that I can't figure out, is that for static binaries(and/orpanic=abort) it still needs the-lunwindlibrary. Nevertheless, It seems like this should be something it finds from the~/.rustup/toolchains/, but nothing I try helpsrustcfind this library?
This allows you to create tables using four different storages and perform operations like JOIN using SQL, all at once. Composite Storage is a versatile feature that can be used in many different scenarios, making it a valuable tool for developers who need to work with multiple storage systems...
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 "...
