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:# rustlang语言零基础快速入门(1) 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 ![](https://img2018.cnblogs.com/blog/544318/201911/544318-20191119111544669-1539794949.png) ![](https://img2018.cnblogs.com/blog/544318/201911/544318-20191119111752805-826086223.png)  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”** ![](https://img2018.cnblogs.com/blog/544318/201911/544318-20191120103110135-538352550.png) 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” ~~~ ![](https://img2018.cnblogs.com/blog/544318/201911/544318-20191120103954112-1485635816.png)  ![](https://img2018.cnblogs.com/blog/544318/201911/544318-20191120104027408-1155904162.png) ~~~ 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: ~~~ ![](https://img2018.cnblogs.com/blog/544318/201911/544318-20191120111411506-813620503.png) 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。 ~~~
