How to disable workspaces?

[PlayerXYT]

I am trying to setup rust-analyzer for the sole purpose of error detection, but it is expecting a cargo workspace for (I assume) completion and linting. How can I turn this off and only have code sanity checking?

If by error detection you mean type errors etc., it still need a cargo workspace. The only thing it can do without a Cargo workspace is show parse errors.

@ChayimFriedman2 That's all I want, syntax errors.
