  this comment is clearer https://github.com/rust-analyzer/rust-analyzer/issues/1650#issuecomment-518088316
  
  it looks like the problem is that search for `.toml` stops too early, so using both and use first directory with a hit would not work. each project in a workspace have it's own `Cargo.toml`, but there is only one top-level `Cargo.lock`.
