Struct PackStore 

pub struct PackStore { /* private fields */ }

Per-objects/ cache of pack indexes, bytes, MIDX views, and delta-base LRU state.

crate::odb::Odb owns an Arc<PackStore>; Odb clones share it. Independently opened Odb handles for the same path get separate stores. Alternate object directories get separate stores retained on the parent Odb.

Implementations

impl PackStore

pub fn new(objects_dir: PathBuf) -> Self

Create a fresh store for objects_dir (not shared with other independent Odb opens).

pub fn objects_dir(&self) -> &Path

objects/ path for this store.

pub fn has_context() -> bool

Whether this thread already has an active pack-read store context.

pub fn with_context<R>(store: Arc<Self>, f: impl FnOnce() -> R) -> R

Run f with store as the pack-read context on this thread.

pub fn invalidate_packs(&self)

Drop cached pack listings, indexes, pack bytes, and delta bases.

pub fn invalidate_midx(&self)

Drop MIDX bytes and tip cache under this store’s objects/pack/.

pub fn invalidate_all(&self)

Full pack + MIDX invalidation (after repack/gc/index-pack in-process).

pub fn configure_delta_base_from_config(&self, cfg: Option<&ConfigSet>)

Apply core.deltaBaseCacheLimit from config to this store’s delta-base LRU.

pub fn invalidate_all_legacy()

Clear legacy thread-local stores (tests/benches calling crate::pack::clear_pack_cache).
