我們今天來配置下vscode+rust。
vscode開發rust很方便。但配置有點坑,我們都認為vscode很簡單，很完善。
但這里很多同學也出現不少問題。
我們在這里簡單記錄下win7下配置的過程，跟着我一步步來，應該就可打造你的屠龍寶刀。
首先，我們安裝插件：
Rust Extension Pack
Rust Test Explorer
然后打開上一篇文章的工程：
hello-rust，見：https://www.cnblogs.com/gyc567/p/11887935.html
打開command palette (Ctrl-Shift-P）：輸入：build,然后選擇：Tasks: Configure Default Build Task，再選擇：Rust: cargo build
vscode會自動生成一個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
}
}
這里，我們直接按“CTRL+SHIFT+P”,選擇：“Task:Run Build Task”,或者直接按快捷鍵“CTRL+F9”
VSCODE會自動BUILD,並在終端窗口顯示打印結果：
-------------------------------------------------------
> 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.

--------------------------------------------------------------
下面配置測試task:
先在main函數下面增加測試代碼：
#[test]
fn should_fail() {
unimplemented!();
}
保存后，按快捷鍵：“CTRL+SHIFT+P”,輸入：Task,選擇“Tasks: Configure Default Test Task”，然后選擇：“Rust: cargo test”
vscode自動生成：
{
"type": "cargo",
"subcommand": "test",
"problemMatcher": [
"$rustc"
],
"group": {
"kind": "test",
"isDefault": true
}
}
保存后，按按快捷鍵：“CTRL+SHIFT+P”,輸入：Task:Run test Task,回車。
vscode自動運行測試用例，並打印結果：
---------------------------------------
> Executing task: cargo test <
Compiling hello-rust v0.1.0 (E:\code\rustProject\hello-rust)
Finished dev [unoptimized + debuginfo] target(s) in 1.77s

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.
-----------------------------------------------------------
下面繼續配置DEBUG環境。
這里參照這個文章：https://www.forrestthewoods.com/blog/how-to-debug-rust-with-visual-studio-code/
簡單來說，你按如下幾步來配置就可以：
1.安裝：
C/C++ extension.
Native Debug extension
2.在debug面板，新建一個新的配置，如下：
然后選擇：“C++ (Windows)” environment
會自動生成launch.json代碼，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的值改為你自己的exe的路徑，比如我的就是：
${workspaceFolder}/target/debug/hello-rust.exe
這時，你直接按F5,你就進入debug狀態，你現在可以設置斷點了。
如果，你順利走到這一步，恭喜你，你已經基本配置好rust的開發環境。
