git-zero-core 0.2.0

//! 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.
#![no_std]
#![forbid(unsafe_code)]
