Struct SingleLocalPackReader 

pub struct SingleLocalPackReader { /* private fields */ }

Sorted cat-file --batch reader for repos with exactly one local pack (hot-path benchmarks).

Keeps a pack index cursor so probes in non-decreasing OID order avoid repeated binary search.

Implementations

impl SingleLocalPackReader

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

Open when crate::pack_store::PackStore read context matches and one local pack index exists.

Errors

Propagates pack directory read failures from index loading.

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

Open when one local pack exists, optionally ignoring loose objects (commit parent walks).

pub fn read_commit_author_prefix( &mut self, oid: &ObjectId, ) -> Result<Option<&[u8]>>

Inflate the start of commit oid into an internal buffer.

Resolves deltified pack entries via the delta-base cache and prefix delta apply. Returns None when the object is missing, not a commit, or cannot be resolved.

Errors

Propagates pack index and zlib errors.

pub fn read_info(&mut self, oid: &ObjectId) -> Result<ObjectInfo>

Kind and size for oid without loading the object body.

Errors

Same as read_object_info_from_pack_at_offset.

pub fn read_object(&mut self, oid: &ObjectId) -> Result<Object>

Decompress the object for oid.

Errors

Same as read_object_from_pack_at_offset.

pub fn read_object_into( &mut self, oid: &ObjectId, out: &mut Vec<u8>, ) -> Result<ObjectKind>

Like Self::read_object, inflating into out and preserving its capacity when possible.

Delta bases resolved along the way are not added to the delta-base cache.

pub fn pack_offset(&self, oid: &ObjectId) -> Result<Option<u64>>

Pack file offset for oid in this reader’s index, if present.

Errors

Propagates pack index lookup errors.
