rust-analyzer failed to discover workspace in vscode


I'm starting to learn the Rust language and I have an issue with rust-analyzer vscode extension.

This picture doesn't provide me with any additional info about root of the problem. I tried to find articles related to my error, but failed. Please help!

guessing_game directory was created with cargo new guessing_game command


Solution

  • I guess you don't have a Cargo.toml file in your project? The rust-analyzer needs a Cargo.toml to detect the workspace.

    You could create a new rust project with cargo:

    cargo new your-project
    

    cargo will help you create a Cargo.toml file automatically, or you could manually create a Cargo.toml for your existing project.

    If this issue keep popping up, perhaps you could check this Github issue for help.

    Edit:

    You should open your project like this, instead of opening the parent directory of guessing_game. Just try the following steps:

    1. cargo new guessing_game_v2;
    2. then in VSCode, Choose "File" -> "Open Folder.." -> Choose the new guessing_game_v2 folder
    3. and check if it works?

    You should make sure that your Cargo.toml is in the root of workspace.
