Struct LooseObjectStore 

pub struct LooseObjectStore { /* private fields */ }

Implementations

impl LooseObjectStore

pub fn new(objects_dir: impl Into<PathBuf>, format: ObjectFormat) -> Self

pub fn from_git_dir(git_dir: impl AsRef<Path>, format: ObjectFormat) -> Self

pub fn object_path(&self, oid: &ObjectId) -> Result<PathBuf>

pub fn exists(&self, oid: &ObjectId) -> Result<bool>

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

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

The object type and content size of oid from loose storage, inflating only the framing header ("<type> <size>\0") and not the body. Output-limited reads keep miniz from inflating past the header even for large objects. Returns Ok(None) when the loose object is absent.

pub fn object_ids(&self) -> Result<Vec<ObjectId>>

Loose object ids in this store, sorted by hex.

pub fn verify_object( &self, oid: &ObjectId, display_path: &str, ) -> Result<Option<LooseObjectIntegrity>>

fsck’s loose-object integrity probe, mirroring C git’s read_loose_object (object-file.c) as called from fsck_loose (builtin/fsck.c): inflate and parse the file at oid’s loose path, then re-hash its content against the path-derived oid. display_path appears verbatim in the error:-level diagnostics — the path-form messages of read_loose_object (“unable to unpack header of ”), unlike the oid-form messages of the normal read path. Returns Ok(None) when no loose file exists for oid.

Trait Implementations

impl Clone for LooseObjectStore

fn clone(&self) -> LooseObjectStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LooseObjectStore

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

Formats the value using the given formatter.

impl ObjectReader for LooseObjectStore

fn read_object(&self, oid: &ObjectId) -> Result<Arc<EncodedObject>>

fn is_shallow_graft(&self, _oid: &ObjectId) -> bool

Graft-points seam (shallow clones today, replace refs/grafts later): true when history is cut at oid, so every walk must treat the commit as parentless even though its raw body still names parents.

fn has_shallow_grafts(&self) -> bool

Whether this reader has any shallow/graft boundaries at all. Walkers can use this to choose dense graph-only traversal when no boundary can cut parent edges.

fn is_promised_object(&self, _oid: &ObjectId) -> bool

True when oid is covered by a promisor pack. Partial clones are allowed to omit promised objects until a later on-demand fetch hydrates them; ordinary readers keep the default “no promised objects”.

impl ObjectWriter for LooseObjectStore

fn write_object(&self, object: EncodedObject) -> Result<ObjectId>

Write object, returning its id. Takes &self: every implementation’s write state (in-memory map, loose-object cache) is behind interior mutability, so a single handle can interleave reads and writes without a &mut borrow. This lets the merge engine read and write through one db instead of opening a second read-only handle that re-warms the caches.
