visual-studio-code - 如何配置运行/调试栏任务？

Question

在此处按“运行”或“调试”时，如何配置执行的内容？这是我看到的:

> Executing task: cargo run --package myproject --bin myproject <

我试图修改tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cargo",
            "command": "run",
            "problemMatcher": [
                "$rustc"
            ],
            "label": "rust: cargo run",
            "env": {
                "RUST_LOG": "info"
            }
        },
        {
            "type": "cargo",
            "command": "build",
            "problemMatcher": [
                "$rustc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "label": "rust: cargo build",
            "env": {
                "RUST_LOG": "info"
            }
        }
    ]
}

但对任务没有影响。
我正在尝试设置环境变量("RUST_LOG": "info")。

Answer 1

然后使用rust-analyzer
Setting runnable environment variables:
您可以将其添加到您的vscode settings.json中，例如~/.config/Code/User/settings.json

    "rust-analyzer.runnableEnv": {
        "RUST_LOG": "info"
    },

或按ctrl+comma，然后单击Open Settings (JSON)图标的右上角。
然后您对Rust很好:

use std::env;

fn main() -> std::io::Result<()> {
    let key = "RUST_LOG";
    match env::var(key) {
        Ok(val) => println!("{}: {:?}", key, val),
        Err(e) => println!("couldn't interpret {}: {}", key, e),
    }

    Ok(())
}

输出:

RUST_LOG: "info"
