Cannot debug Rust in Visual Studio Code?-CodePudding

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

To debug the code, it is necessary to create a launch.json file, using Run - Add configuration... However, the file isn't correct, with <your program> where the correct name should be. This is the wrong approach.

{

"version": "0.2.0",
"configurations": [
    {
        "type": "lldb",
        "request": "launch",
        "name": "Debug",
        "program": "${workspaceFolder}/<your program>",
        "args": [],
        "cwd": "${workspaceFolder}"
    }
]

}

The documentation is a bid thin at this point. The correct approach is to pick a different folder, the top level of the project hello_world. The Cargo.toml file is available.

Now, when Run - Add configuration... is used, and the option of LLDB is selected -

the Cargo.toml file can be picked up -

and then the Cargo.toml file is used to correctly build the launch.json file -

  "version": "0.2.0",
  "configurations": [
     {
        "type": "lldb",
        "request": "launch",
        "name": "Debug executable 'hello_world'",
        "cargo": {
            "args": [
                "build",
                "--bin=hello_world",
                "--package=hello_world"
            ],
            "filter": {
                "name": "hello_world",
                "kind": "bin"
            }
        },
        "args": [],
        "cwd": "${workspaceFolder}"
    },
    {
        "type": "lldb",
        "request": "launch",
        "name": "Debug unit tests in executable 'hello_world'",
        "cargo": {
            "args": [
                "test",
                "--no-run",
                "--bin=hello_world",
                "--package=hello_world"
            ],
            "filter": {
                "name": "hello_world",
                "kind": "bin"
            }
        },
        "args": [],
        "cwd": "${workspaceFolder}"
    }
]
}

Now, both Run - Start debugging and Run - Run without Debugging both work properly.
