uv-extract

crates/uv-extract/ extracts archives — wheels (zip), source distributions (.tar.gz/.tar.bz2/.tar.xz/.tar.zst/.zip.zst) — with concurrent hashing.

Purpose

Most archive operations in uv need to compute hashes while extracting, both for cache content-addressing and for the resolver's hash strategy. This crate provides streaming extraction that hashes on the fly.

Key abstractions

• Hasher — wraps a hash algorithm and a digest in progress.
• HashReader — wraps an AsyncRead to feed bytes into a Hasher while passing them through.
• Functions that extract a .whl or sdist to a target directory while populating a hash.

• uv-cache — extraction is the producer; cache is the consumer.
