Modern debugging Rust projects in VSCode

Introduction

I won’t bug you with an explanation, at this level you should be perfectly knowledgeable to reason and be able to retrieve information from the internet as efficiently as possible. I won't even blame if you don't read this paragraph, just go copy-and-paste config I've provided below this wall of text.

The config

1. Setup a .vscode/tasks.json file in your project, don't forget to add it to .gitignore. It will include a job that will build your rust project every time you start a debugging session.

2. Setup a .vscode/launch.json as well. It will be responsible for launching the debugging session. Notice that you will need to change 2 things in launch.json: program argument, replace <your_binary> with well... you know. Secondly, remove or edit args to pass your arguments to the program.

3. Run with F5, you should be good to go.

.vscode/tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "rust: cargo build",
            "type": "cargo",
            "command": "build",
            "problemMatcher": [
                "$rustc"
            ],
            "group": "build"
        }
    ]
}

.vscode/lauch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "Run app with test args",
            "program": "${workspaceFolder}/target/debug/<your_binary>",
            "args": ["--config", "./etc/config.dev.toml"],
            "cwd": "${workspaceFolder}",
            "preLaunchTask": "rust: cargo build"
        }
    ]
}
