Struct LoadedPackBitmap 

pub struct LoadedPackBitmap { /* private fields */ }

A pack’s .bitmap loaded for consultation: oid <-> pack-position mappings, resolved (XOR-expanded) per-commit reachability bitsets, and the four object type bitmaps. Bit numbering follows pack order throughout.

Implementations

impl LoadedPackBitmap

pub fn object_count(&self) -> u32

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

Pack-order position of oid, when the object is in the bitmapped pack.

pub fn oid_at(&self, position: u32) -> Option<&ObjectId>

pub fn bitmap_for_commit(&self, oid: &ObjectId) -> Option<&Arc<Vec<u64>>>

The resolved reachability bitset stored for oid, when it was one of the writer’s selected commits.

pub fn bitmapped_commits(&self) -> impl Iterator<Item = &ObjectId>

Oids of every commit with a stored bitmap entry (unordered).

pub fn pseudo_merge_count(&self) -> usize

pub fn pseudo_merge_words(&self, index: usize) -> Option<(&[u64], &[u64])>

pub fn type_words(&self, object_type: ObjectType) -> &[u64]

The type bitmap for object_type (bit per pack position).
