Struct PackManager 

pub struct PackManager { /* private fields */ }

Format-only coordinator for loaded pack and index files.

Object-domain indexes belong in a wrapper owned by the consuming crate.

Implementations

impl PackManager

pub fn new(packs_dir: PathBuf) -> PackManager

pub fn reload(&mut self) -> Result<(), HeddleError>

pub fn add_pack( &mut self, pack_path: PathBuf, index_path: PathBuf, ) -> Result<(), HeddleError>

Add a complete pack/index pair to the in-memory format index.

pub fn needs_reload(&self) -> Result<bool, HeddleError>

Cheap check: does the packs directory hold more pack/index pairs than we have loaded? Reuses discover_pack_paths so half-installed packs (a .pack whose .idx sibling hasn’t landed yet) are filtered out — otherwise we’d loop forever reloading a count we can never match.

pub fn reload_if_disk_grew(&mut self) -> Result<bool, HeddleError>

Reload the pack list only if the packs directory has more pack/index pairs on disk than we know about in memory.

Catches the multi-instance case: two FsStores back the same shared object dir (typical for lightweight thread worktrees, where the worktree’s repo opens its own store but points at the main repo’s .heddle/). When the worktree’s store installs a new pack, the main repo’s already-open pack_manager doesn’t know about it; without this get_blob/has_blob from the main repo would surface “object not found”.

pub fn get_object( &self, id: &PackObjectId, ) -> Result<Option<(ObjectType, Vec<u8>)>, HeddleError>

pub fn get_hashed_object( &self, hash: &ContentHash, ) -> Result<Option<(ObjectType, Vec<u8>)>, HeddleError>

pub fn get_hashed_object_bytes( &self, hash: &ContentHash, ) -> Result<Option<(ObjectType, Bytes)>, HeddleError>

Zero-copy variant of get_hashed_object. Returns bytes::Bytes views into the underlying pack mmap when the entry is non-delta and stored uncompressed; falls back to the standard decompress-into-Vec path otherwise.

pub fn has_object(&self, hash: &ContentHash) -> bool

pub fn get_hashed_object_size( &self, hash: &ContentHash, ) -> Result<Option<u64>, HeddleError>

Look up the uncompressed size of hash across all loaded packs without decompressing the payload. Returns Ok(None) when the object isn’t in any loaded pack.

pub fn has_object_id(&self, id: &PackObjectId) -> bool

pub fn list_all_hashes(&self) -> Result<Vec<ContentHash>, HeddleError>

List all object hashes across all packs.

pub fn list_all_ids(&self) -> Result<Vec<PackObjectId>, HeddleError>

pub fn pack_file_paths(&self) -> Vec<(&Path, &Path)>

Return paths of all pack files (for deletion during aggressive repack).

pub fn pack_count(&self) -> usize

pub fn packs_dir(&self) -> &Path
