Cannot debug Rust in Visual Studio Code?

Question

I am trying to debug a Rust program in VS Code, but I get an error:

After clicking OK, VS Code opens "settings.json":

I have these extensions installed:

My program is a simple "hello world" app.

Answer 1

Unfortunately VS Code can't debug Rust out of the box :( But no need to worry, just few steps of configuration will do the work :)

Steps

1. Install C/C++ extension if you are on windows and CodeLLDB if on OS X/Linux

2. Click Debug -> Add Configuration, a launch.json file should open, you need to change the program name here manually

    {
        "version": "0.2.0",
        "configurations": [
            {
                "name": "(Windows) Launch",
                "type": "cppvsdbg",
                "request": "launch",
                "program": "${workspaceRoot}/target/debug/foo.exe",
                "args": [],
                "stopAtEntry": false,
                "cwd": "${workspaceRoot}",
                "environment": [],
                "externalConsole": true
            },
            {
                "name": "(OSX) Launch",
                "type": "lldb",
                "request": "launch",
                "program": "${workspaceRoot}/target/debug/foo",
                "args": [],
                "cwd": "${workspaceRoot}",
            }
        ]
    }
   

3. Make sure Allow setting breakpoints in any file is checkend under File -> Preferences -> Settings
