pub fn deregister_in(
cache_dir: &Path,
project_root: &Path,
phase: PhaseId,
) -> Result<(), RegistryError>Expand description
Remove the entry file for (project_root, phase), if present. With the
per-file storage shape this is a single remove_file on
entry_path_in — no load, no rewrite, and therefore no way to
disturb a sibling entry belonging to another phase or another root. A
missing file (never registered, or already deregistered) is treated as
success rather than an error.
