Struct CommitGraphChain 

pub struct CommitGraphChain { /* private fields */ }

Loaded commit-graph chain (newest layer first, matching commit-graph-chain file order).

Implementations

impl CommitGraphChain

pub fn top_layer_bloom_settings(&self) -> Option<BloomFilterSettings>

Bloom settings from the newest layer, if that layer carries Bloom data.

pub fn total_commits(&self) -> u32

Total commits across all layers (Git num_commits_in_base offset for new layers).

pub fn layer_paths_oldest_first(&self) -> Vec<PathBuf>

Layer file paths from oldest base to newest (reverse of chain file order).

pub fn try_load(objects_dir: &Path) -> Result<Option<Self>, Error>

Load from objects/info/commit-graph or objects/info/commit-graphs/commit-graph-chain.

Returns Ok(None) when no commit-graph exists. Corrupt graphs (including invalid GDO2) return Err.

pub fn load(objects_dir: &Path) -> Option<Self>

Like Self::try_load but ignores parse errors (returns None).

pub fn find_commit(&self, oid: &ObjectId) -> Option<(usize, u32)>

Lexicographic position in the full chain, or None if not in any layer.

pub fn global_position(&self, oid: &ObjectId) -> Option<u32>

Global commit-graph position (Git graph_pos): base layers first, then newer layers.

pub fn all_oids_in_order(&self) -> Vec<ObjectId>

All commit OIDs in the chain (oldest base first, then newer layers).

pub fn bloom_precheck_for_paths( &self, odb: &Odb, oid: ObjectId, pathspecs: &[String], bloom_cwd: Option<&str>, requested_hash_version: i32, read_changed_paths: bool, ) -> Result<BloomPrecheck, Error>

Consult Bloom filters for a single-parent commit before diffing trees.

Trait Implementations

impl Clone for CommitGraphChain

fn clone(&self) -> CommitGraphChain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommitGraphChain

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