Description
When opening stand-alone .rs files that are not contained in a Cargo project, rust-analyzer stops and gives the error "rust-analyzer failed to discover workspace". This is kind of annoying when the file is not intended to be in any Cargo workspace, but intended to be compiled directly with rustc.
There are some previous issues (#9082, #9089) that apparently fixed this, but I'm getting the error still today so I suppose there could have been a regression since then.

Research direction
Start by reproducing the error when opening a stand-alone .rs file outside a Cargo workspace, then review the related issues #9082 and #9089 for the earlier behavior and expected handling. Done means stand-alone files no longer fail workspace discovery when they are intended to be compiled directly with rustc.
