[易学易懂系列|rustlang语言|零基础|快速入门|(2)|VSCODE配置]

我们今天来配置下vscode+rust。

vscode开发rust很方便。但配置有点坑,我们都认为vscode很简单,很完善。

但这里很多同学也出现不少问题。

我们在这里简单记录下win7下配置的过程,跟着我一步步来,应该就可打造你的屠龙宝刀。

首先,我们安装插件:

Rust Extension Pack
Rust Test Explorer
 
然后打开上一篇文章的工程:hello-rust,见:https://www.cnblogs.com/gyc567/p/11887935.html
打开command palette (Ctrl-Shift-P):输入:build,然后选择:Tasks: Configure Default Build Task,再选择:Rust: cargo build

 

 

 vscode会自动生成一个json文件:

 // See https://go.microsoft.com/fwlink/?LinkId=733558 
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "cargo run",
            "type": "shell",
            "command": "cargo",
            "args": [
                "run"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
 
 
 这里,我们直接按“CTRL+SHIFT+P”,选择:“Task:Run Build Task”,或者直接按快捷键“CTRL+F9”
 

 

 

VSCODE会自动BUILD,并在终端窗口显示打印结果:
-------------------------------------------------------
> Executing task: cargo run <

   Compiling hello-rust v0.1.0 (E:\code\rustProject\hello-rust)
    Finished dev [unoptimized + debuginfo] target(s) in 2.11s
     Running `target\debug\hello-rust.exe`
----------------------------
| Hello fellow Rustaceans! |
----------------------------
              \
               \
                  _~^~^~_
              \) /  o o  \ (/
                '_   -   _'
                / '-----' \

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

 下面配置测试task:

先在main函数下面增加测试代码:

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

保存后,按快捷键:“CTRL+SHIFT+P”,输入:Task,选择“Tasks: Configure Default Test Task”,然后选择:“Rust: cargo test”

 

 

 

 

 


vscode自动生成:
{
            "type": "cargo",
            "subcommand": "test",
            "problemMatcher": [
                "$rustc"
            ],
            "group": {
                "kind": "test",
                "isDefault": true
            }
        }

 

 

保存后,按按快捷键:“CTRL+SHIFT+P”,输入:Task:Run test Task,回车。
vscode自动运行测试用例,并打印结果:

---------------------------------------

> Executing task: cargo test <

   Compiling hello-rust v0.1.0 (E:\code\rustProject\hello-rust)
    Finished dev [unoptimized + debuginfo] target(s) in 1.77s
     Running target\debug\deps\hello_rust-bfa762df5afd173e.exe

running 1 test
test should_fail ... FAILED

failures:

---- should_fail stdout ----
thread 'should_fail' panicked at 'not yet implemented', src\main.rs:14:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.


failures:
    should_fail

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

error: test failed, to rerun pass '--bin hello-rust'
The terminal process terminated with exit code: 1

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

下面继续配置DEBUG环境。
这里参照这个文章:https://www.forrestthewoods.com/blog/how-to-debug-rust-with-visual-studio-code/
简单来说,你按如下几步来配置就可以:
1.安装:
C/C++ extension.
Native Debug extension
2.在debug面板,新建一个新的配置,如下:

 

然后选择:“C++ (Windows)” environment

 

会自动生成launch.json代码,如下 :

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        

        {
            "name": "(Windows) Launch",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "${workspaceFolder}/target/debug/hello-rust.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false
        }
    ]
}

其中program的值改为你自己的exe的路径,比如我的就是:

${workspaceFolder}/target/debug/hello-rust.exe
这时,你直接按F5,你就进入debug状态,你现在可以设置断点了。


如果,你顺利走到这一步,恭喜你,你已经基本配置好rust的开发环境。
