Module pack 

Pack file encoder/decoder implementations, caches, waitlists, and stream wrappers that faithfully follow the pack-format spec.

Modules

cache

Multi-tier cache for pack decoding that combines an in-memory LRU with spill-to-disk storage and bookkeeping for concurrent rebuild tasks.

cache_object

Cache object representation plus disk-backed serialization helpers used by the pack decoder to bound memory while still serving delta reconstruction quickly.

channel_reader

Simple channel-backed BufRead adapter so pack decoding can consume data streamed from async tasks or background threads.

decode

Streaming pack decoder that validates headers, inflates entries, rebuilds deltas (including zstd), and populates caches/metadata for downstream consumers.

encode

Pack encoder capable of building streamed .pack/.idx pairs with optional delta compression, windowing, and asynchronous writers.

entry

Lightweight representation of a decoded Git object coming out of a pack stream, with helpers to convert to/from strongly typed objects.

pack_index

Builder for Git pack index (.idx) files that streams fanout tables, CRCs, offsets, and trailer hashes through an async channel.

utils

Shared pack-parsing helpers for reading object headers, varints, offsets, and zlib-compressed payloads as defined by Git’s pack format.

waitlist

Temporary storage for delta objects while their base object is still decoding, keyed by both pack offset and object hash.

wrapper

Reader wrapper that tracks how many bytes of a pack have been consumed while keeping a running SHA-1/SHA-256 hash for trailer verification.

Structs

Pack

Representation of a Git pack file in memory.
