Struct jj_lib::default_index::CompositeIndex

pub struct CompositeIndex<'a>(/* private fields */);

Reference wrapper that provides global access to nested index segments.

Trait Implementations

impl AsCompositeIndex for CompositeIndex<'_>

fn as_composite(&self) -> CompositeIndex<'_>

Returns reference wrapper that provides global access to this index.

impl<'a> Clone for CompositeIndex<'a>

fn clone(&self) -> CompositeIndex<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'index> IdIndexSource<IndexPosition> for CompositeIndex<'index>

type Entry = IndexEntry<'index>

fn entry_at(&self, pointer: &IndexPosition) -> Self::Entry

impl Index for CompositeIndex<'_>

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

Suppose the given commit_id exists, returns the minimum prefix length to disambiguate it. The length to be returned is a number of hexadecimal digits.

If the given commit_id doesn’t exist, this will return the prefix length that never matches with any commit ids.

fn topo_order( &self, input: &mut dyn Iterator<Item = &CommitId> ) -> Vec<CommitId>

Parents before children

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

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

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

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

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, candidate_ids: &mut dyn Iterator<Item = &CommitId> ) -> Vec<CommitId>

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