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

下面配置测试task:
先在main函数下面增加测试代码：
2
3
4
5
6
7
2fn should_fail() {
3 unimplemented!();
4}
5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”

21下面继续配置DEBUG环境。
22这里参照这个文章：https://www.forrestthewoods.com/blog/how-to-debug-rust-with-visual-studio-code/
23简单来说，你按如下几步来配置就可以：
241.安装：
25C/C++ extension.
26Native Debug extension
272.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.

"args": [],
