}

Mutable per-iter_changes state shared across super::DirState::process_entry calls. Ports the instance fields Python’s ProcessEntryPython carries: search / searched sets, parent-id caches, dirname-to-file-id maps.

Fields

source_index: Option<usize>

source_index in the tree-data array; None means “compare against a synthetic empty source” (new-tree mode).

target_index: usize

target_index in the tree-data array; always concrete.

include_unchanged: bool

Whether unchanged entries should still yield a change tuple.

want_unversioned: bool

Whether the iter_changes caller wants reports for paths on disk that aren’t in either source or target dirstate trees.

partial: bool

Partial iter_changes: true when the caller supplied a narrower set of paths than {b""}. Used by _gather_result_for_consistency to decide whether to queue parent-directory bookkeeping.

supports_tree_reference: bool

Whether the current working-tree format supports tree references. When false, is_tree_reference_dir is never called during the walk.

root_abspath: Vec<u8>

Absolute path of the working-tree root on disk. Used to join root + relpath into an absolute path that Transport methods can accept. Filled at iter_changes call time.

searched_specific_files: HashSet<Vec<u8>>

Paths whose children have already been walked.

search_specific_files: HashSet<Vec<u8>>

Paths whose children still need walking (driven by the outer iter_changes loop).

search_specific_file_parents: HashSet<Vec<u8>>

Parent directories we need to re-visit after the main walk — populated by _gather_result_for_consistency when a partial iter_changes produces a relocated entry.

searched_exact_paths: HashSet<Vec<u8>>

Paths we’ve examined via _iter_specific_file_parents.

seen_ids: HashSet<Vec<u8>>

File ids we’ve already yielded during the main walk.

new_dirname_to_file_id: HashMap<Vec<u8>, Vec<u8>>

Cache: dirname → file_id for the target tree.

old_dirname_to_file_id: HashMap<Vec<u8>, Vec<u8>>

Cache: dirname → file_id for the source tree.

last_source_parent: Option<(Vec<u8>, Option<Vec<u8>>)>

One-slot cache: (dirname, parent_file_id) for the source tree.

last_target_parent: Option<(Vec<u8>, Option<Vec<u8>>)>

One-slot cache: (dirname, parent_file_id) for the target tree.
