Struct DefaultReadonlyIndex 

pub struct DefaultReadonlyIndex(/* private fields */);

Commit index backend which stores data on local disk.

Implementations

impl DefaultReadonlyIndex

pub fn num_commits(&self) -> u32

Returns the number of all indexed commits.

pub fn stats(&self) -> IndexStats

Collects statistics of indexed commits and segments.

pub fn generation_number(&self, commit_id: &CommitId) -> Option<u32>

Looks up generation of the specified commit.

Trait Implementations

impl Clone for DefaultReadonlyIndex

fn clone(&self) -> DefaultReadonlyIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DefaultReadonlyIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Index for DefaultReadonlyIndex

fn shortest_unique_commit_id_prefix_len( &self, commit_id: &CommitId, ) -> IndexResult<usize>

Returns the minimum prefix length to disambiguate commit_id from other commits in the index. The length returned is the number of hexadecimal digits in the minimum prefix.

fn resolve_commit_id_prefix( &self, prefix: &HexPrefix, ) -> IndexResult<PrefixResolution<CommitId>>

Searches the index for commit IDs matching prefix. Returns a PrefixResolution with a CommitId if the prefix matches a single commit.

fn has_id(&self, commit_id: &CommitId) -> IndexResult<bool>

Returns true if commit_id is present in the index.

fn is_ancestor( &self, ancestor_id: &CommitId, descendant_id: &CommitId, ) -> IndexResult<bool>

Returns true if ancestor_id commit is an ancestor of the descendant_id commit, or if ancestor_id equals descendant_id.

fn common_ancestors( &self, set1: &[CommitId], set2: &[CommitId], ) -> IndexResult<Vec<CommitId>>

Returns the best common ancestor or ancestors of the commits in set1 and set2. A “best common ancestor” has no descendants that are also common ancestors.

fn all_heads_for_gc( &self, ) -> IndexResult<Box<dyn Iterator<Item = CommitId> + '_>>

Heads among all indexed commits at the associated operation.

fn heads( &self, candidates: &mut dyn Iterator<Item = &CommitId>, ) -> IndexResult<Vec<CommitId>>

Returns the subset of commit IDs in candidates which are not ancestors of other commits in candidates. If a commit id is duplicated in the candidates list it will appear at most once in the output.

fn changed_paths_in_commit( &self, commit_id: &CommitId, ) -> IndexResult<Option<Box<dyn Iterator<Item = RepoPathBuf> + '_>>>

Returns iterator over paths changed at the specified commit. The paths are sorted. Returns None if the commit wasn’t indexed.

fn evaluate_revset( &self, expression: &ResolvedExpression, store: &Arc<Store>, ) -> Result<Box<dyn Revset + '_>, RevsetEvaluationError>

Resolves the revset expression against the index and corresponding store.

impl ReadonlyIndex for DefaultReadonlyIndex

fn as_index(&self) -> &dyn Index

fn change_id_index( &self, heads: &mut dyn Iterator<Item = &CommitId>, ) -> Box<dyn ChangeIdIndex>

fn start_modification(&self) -> Box<dyn MutableIndex>
