Function prune_packed_objects 

pub fn prune_packed_objects(
    objects_dir: &Path,
    opts: PrunePackedOptions,
) -> Result<Vec<PathBuf>>

Remove loose objects that are already stored in a pack file.

For each loose object under objects_dir whose ObjectId appears in at least one local pack index, the file is deleted (or, with PrunePackedOptions::dry_run, the deletion command is printed to stdout). Empty two-char prefix directories are removed afterwards.

Returns the list of paths that were (or would be) removed.

Errors

• Error::Io for directory or file access failures.
