Hello, it seems that there's a temporary file src/.write.rs.pending-snap created by the insta crate that's not in the .gitignore.
While I'm not familiar with the insta crate, but it seems that, from reading the documentation, the .pending-snap files are 'draft' files, 'draft' probably meaning 'temporary' and those that shouldn't be committed to a repository. This is also fits with the popular rust-analyzer project having the **/*.rs.pending-snap line in its .gitignore.
