03.debug rust lang in vscode

[zhao-core]

vscode rust

使用vscode对rust开发调试
首先安装rust插件
Rust
Rust Extension Pack
Rust Test Explorer

配置开发

以Mac为例，cmd + shirft + p打开命令面板，输入：

tasks

选择 Tasks: Configure Default Build Task，再选择：Rust: cargo build

vscode就会生成：.vscode/tasks.json

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558 
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "type": "cargo",
      "subcommand": "build",
      "problemMatcher": [
        "$rustc"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      }
    }
  ]
}

将"subcommand": "build" 改成 ："subcommand": "run"
这样按cmd + shirft + B，就能直接运行:

> Executing task: cargo run <

    Finished dev [unoptimized + debuginfo] target(s) in 0.00s
     Running `target/debug/vscode-rust`
Hello, world!

Terminal will be reused by tasks, press any key to close it.

配置测试task

在src/main.rs添加测试方法：

#[test]
fn fail() {
    unimplemented!();
}

以Mac为例，cmd + shirft + p打开命令面板，输入：

tasks

选择 Tasks: Configure Default Test Task，再选择：Rust: cargo test

> Executing task: cargo test <

   Compiling vscode-rust v0.1.0 (/Users/zhaoxiongliang/work/github/jsl6/rust-learn/03-vscode-rust)
    Finished test [unoptimized + debuginfo] target(s) in 0.44s
     Running target/debug/deps/vscode_rust-e3d6a94d5c6c8ae6

running 1 test
test fail ... FAILED

failures:

---- fail stdout ----
thread 'fail' panicked at 'not yet implemented', src/main.rs:6:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.


failures:
    fail

test result: FAILED. 0 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out

error: test failed, to rerun pass '--bin vscode-rust'
The terminal process terminated with exit code: 101

Terminal will be reused by tasks, press any key to close it.

Debug环境

安装：
C/C++ extension.
Native Debug

!在Debug菜单，Add Congfigration,选择“C++ (Windows)” environment"
debug
生成

  // Hover to view descriptions of existing attributes.

  "version": "0.2.0",
  "configurations": [
    {
      "name": "(lldb) 启动",
      "type": "cppdbg",
      "request": "launch",
      "program": "${workspaceFolder}/a.out",
      "args": [],
      "stopAtEntry": false,
      "cwd": "${workspaceFolder}",
      "environment": [],
      "externalConsole": false,
      "MIMode": "lldb"
    }
  ]
}

将"program": "${workspaceFolder}/a.out",改成：

"program": "${workspaceFolder}/target/debug/vscode-rust",

在main.rs打上断点，在debug模式下启动，就能进入程序调试：
