Struct DefaultMutableIndex

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

In-memory mutable records for the on-disk commit index backend.

Trait Implementations

impl AsCompositeIndex for DefaultMutableIndex

fn as_composite(&self) -> &CompositeIndex

Returns reference wrapper that provides global access to this index.

impl Index for DefaultMutableIndex

fn shortest_unique_commit_id_prefix_len(&self, commit_id: &CommitId) -> 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, ) -> 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) -> bool

Returns true if commit_id is present in the index.

fn is_ancestor(&self, ancestor_id: &CommitId, descendant_id: &CommitId) -> 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], ) -> 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, ) -> Result<Box<dyn Iterator<Item = CommitId> + '_>, AllHeadsForGcUnsupported>

Heads among all indexed commits at the associated operation.

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

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

Resolves the revset expression against the index and corresponding store.

impl MutableIndex for DefaultMutableIndex

fn as_any(&self) -> &dyn Any

fn into_any(self: Box<Self>) -> Box<dyn Any>

fn as_index(&self) -> &dyn Index

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

fn add_commit(&mut self, commit: &Commit)

fn merge_in(&mut self, other: &dyn ReadonlyIndex)
