新建 .vscode 文件夹

添加 tasks.json 文件：

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

windows上）添加 launch.json 文件

{
    "version": "0.2.0",
    "configurations": [{
            "name": "(Windows) 启动",
            "preLaunchTask": "build",
            "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/${workspaceFolderBasename}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "这里填GDB所在的目录",
            "setupCommands": [{
                "description": "为 gdb 启用整齐打印",
                "text": "-enable-pretty-printing",
                "ignoreFailures": true
            }]
        }
    ]
}

linux下的launch.json

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

mac os 上的 launch.json

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