pub fn orphan_workspaces(
workspace_root: &Utf8Path,
branches: &[BranchInstance],
) -> Result<(Vec<Utf8PathBuf>, Vec<String>)>Expand description
Workspace directories under workspace_root that no binding record
claims. A workspace is a cache, so an unclaimed one is just garbage —
but only the records can say which ones are claimed.
Deletion is deliberately narrower than “unclaimed”: a directory is
removed only if newgit can prove it made it (it carries a workspace
marker) or there is nothing to lose (it is empty). [workspace] root is
user-configurable and might point somewhere shared, and “newgit deleted a
directory it did not create” is not a failure mode worth risking to
reclaim disk. Anything else is reported as unrecognized and left alone.
