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 ustProjecthello-rust)
Finished dev [unoptimized + debuginfo] target(s) in 2.11s
Running `targetdebughello-rust.exe`
----------------------------
| Hello fellow Rustaceans! |
----------------------------
_~^~^~_
) / o o (/
'_ - _'
/ '-----'
Terminal will be reused by tasks, press any key to close it.

_~^~^~_
) / 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 ustProjecthello-rust)
Finished dev [unoptimized + debuginfo] target(s) in 1.77s

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。
