RUST 环境配置

Rust 安装 (Windows)

1. 运行 rustup-init.exe 前先执行以下命令，设置环境变量，加速下载

     set CARGO_HOME=D:\Rust\.cargo
     set RUSTUP_HOME=D:\Rust\.rustup
     set RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
     set RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup
   

   分别设置了安装目录，和下载镜像地址，设置好后，回车安装即可

2. 安装完成后 在 %CARGO_HOME% 目录创建文件 config, 该文件没有后缀, 内容填写如下

   [source.crates-io]
   registry = "https://github.com/rust-lang/crates.io-index"
   replace-with = 'ustc'
   [source.ustc]
   registry = "https://mirrors.ustc.edu.cn/crates.io-index/"
   

3. 环境变量配置 在系统属性环境变量中添加如下信息。
   CARGO_HOME=D:\Rust\.cargo
   RUSTUP_HOME=D:\Rust\.rustup
   RUSTUP_DIST_SERVER=http://mirrors.ustc.edu.cn/rust-static
   RUSTUP_UPDATE_ROOT=http://mirrors.ustc.edu.cn/rust-static/rustup
   PATH 中追加 %CARGO_HOME%\bin
   

4. 创建工程

   cargo new greeting
   

VSCode 配置

1. 安装插件 rust-analyzer 和 Native Debug
2. tasks.json 配置

   {
    "version": "2.0.0",
    "tasks": [

            "label": "build",
            "type": "shell",
            "command": "cargo",
            "args": [
                "build"
            ]
        }
    ]
   }
   

3. launch.json 配置

   {
    "version": "0.2.0",
    "configurations": [
        {

            "type": "cppvsdbg",
            "request": "launch",
            "program": "${workspaceFolder}/target/debug/${workspaceFolderBasename}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false
        },
        {
            "name": "(gdb)启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/target/debug/${workspaceFolderBasename}.exe",
            "args": [],
