Rust从入门到暴走（3）--- Rust开发环境搭建Visual Studio Code

通过上篇文章相信大家已经学会了如何通过命令行的形式编译Rust代码文件并且运行，今天我们来学习如何搭建好自己的的开发环境，这里选用的是Visual Studio Code

下载Visual Studio Code

Visual Studio Code：Download Visual Studio Code - Mac, Linux, Windows

启动Visual Studio Code

下载完 Visual Studio Code 安装包之后启动安装向导安装。 安装完 Visual Studio Code （下文简称 VSCode）之后运行 VSCode。

安装插件

rust analyzer & native debug (安装好，重启VSCode就可以)

创建项目

Terminal--->New Terminal

创建Rust的项目demo

luca@LucadeMacBook-Air rust-workspace % cargo new demo    
     Created binary (application) `demo` package
luca@LucadeMacBook-Air rust-workspace % ls -a
.       ..      demo
luca@LucadeMacBook-Air rust-workspace % 

Cargo构建和运行

Cargo 是Rust 编译器Rust的构建工具和前端，以及软件包和依赖项管理器。 它允许Rust 项目声明具有特定版本要求的依赖关系，解析完整依赖项图、下载软件包和构建，以及测试整个项目。

luca@LucadeMacBook-Air rust-workspace % cd demo
luca@LucadeMacBook-Air demo % 
luca@LucadeMacBook-Air demo % cargo build 
   Compiling demo v0.1.0 (/Users/luca/dev/rust-workspace/demo)
    Finished dev [unoptimized + debuginfo] target(s) in 5.45s
luca@LucadeMacBook-Air demo % 
luca@LucadeMacBook-Air demo % cargo run 
    Finished dev [unoptimized + debuginfo] target(s) in 0.00s
     Running `target/debug/demo`
Hello, world!

VSCode界面运行

通过VSCode打开项目demo

项目目录结构，通过VSCode运行代码文件

VSCode集成Debug

在demo目录里面新建.vscode文件夹，加入tasks.json和launch.json

task.json

{
    "version": "2.0.0",
    "tasks": [
      {
        "label": "build",
        "type": "shell",
        "command": "cargo",
        "args": [
          "build"
        ]
      }
    ]
  }

launch.json

对于 Mac OS

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "lldb launch",
            "type": "cppdbg",
            "preLaunchTask": "build",
            "request": "launch",
            "program": "${workspaceFolder}/target/debug/${workspaceFolderBasename}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "lldb"
        }
    ]
}

对于 Linux

 
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug",
            "type": "gdb",
            "preLaunchTask": "build",
            "request": "launch",
            "target": "${workspaceFolder}/target/debug/${workspaceFolderBasename}",
            "cwd": "${workspaceFolder}"
        }
    ]
}

对于 Windows

{ 
    "version": "0.2.0", 
    "configurations": [ 
        { 
            "name": "Windows launch",

            "type": "cppvsdbg", 
            "request": "launch", 
            "program": "${workspaceFolder}/target/debug/${workspaceFolderBasename}.exe", 
            "args": [], 
            "stopAtEntry": false, 
            "cwd": "${workspaceFolder}", 
            "environment": [], 
            "externalConsole": false 
        }, 
        { 
            "name": "gdb launch", 
            "type": "cppdbg", 
            "request": "launch", 
            "program": "${workspaceFolder}/target/debug/${workspaceFolderBasename}.exe", 
            "args": [], 
            "stopAtEntry": false, 
            "cwd": "${workspaceFolder}", 
            "environment": [], 
            "externalConsole": false, 
            "MIMode": "gdb", 
            "miDebuggerPath": "这里填GDB所在的目录",
