CodePudding user response：

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.

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