Crate git_zero_core 

Allocation-free Git objects, repositories and wire primitives.

read enables inflation, pack decoding and repository validation. write enables snapshots, pack/zlib encoding and pack caching.

Storage and I/O belong to the caller. There is no std, alloc, allocator, global state, filesystem, or socket dependency in this crate.

Modules

cache

checkout

Borrowed file contents and bounded checkout traversal for caller-owned stores.

http

Shared HTTP request and response values; framing belongs to the host.

io

object

pack

pktline

reader

Bounded object reads and resumable repository-format hashing. State is inline; callers own the body buffer and can retain state between individual steps.

repository

Immutable object/ref providers, HEAD states, ref validation and symbolic resolution. Fetch graph validation and selection live in validation.

snapshot

validation

Object/link validation and bounded reachable-object selection for upload-pack. ValidatedRepository shares its authenticated index with fetch history traversal. Opt-in validation of the repository graph contract, without allocation.

zlib

Allocation-free streaming zlib encoding and inflation (RFC 1950/1951). The encoder uses stored blocks; the decoder also accepts fixed and dynamic Huffman blocks, with caller-owned history and explicit expansion budgets. The decoder is implemented from RFC 1950 and RFC 1951.

Structs

FetchOptions

Bounded history and object selection, sharing the ordinary graph-read budget.

HistoryPolicy

History decisions for an external, host-owned graph frontier. The host supplies the shortest commit distance from wanted roots (starting at one) and persists deduplication, exclusions and work budgets outside this value.

Enums

BlobFilter

Partial-clone object policies. Explicitly wanted objects are retained.
