# ── donation shape (D21) ────────────────────────────────────────────────────
#
# Dependency versions are written out here rather than inherited from the
# workspace on purpose: this crate must be liftable out of gunnar's tree with
# `cp -r` and build unchanged. `version.workspace = true` would make the
# manifest meaningless outside this repository, which is exactly the coupling
# D21 exists to prevent. The package metadata is spelled out for the same
# reason.
#
# There is deliberately NO gunnar dependency, and there never may be one.
# `crates/gunnar-delta/tests/donation_shape.rs` asserts it.

# Object identity and kind: the only two things the window search needs to know
# about a git object besides its bytes.

# `parallel` is what makes `in_parallel_with_slice` the threaded implementation
# rather than a `for` loop; without it the whole crate is silently serial and
# nothing warns (P-002 in `.nornir/performance-design.md`, the same trap one
# crate over). `progress` gives the `prodash` re-exports.

# Round-trip verification goes through gix's OWN decoder, never this crate's:
# `gix_pack::data::File::decode_entry`. `gix_pack::data::delta::apply` is
# `pub(crate)`, so the only reachable decoder is the one that reads a real
# packfile, which is why `tests/support/pack.rs` writes real packs.

# Runtime-detected SIMD for the match scan. Off means the portable word-at-a-time
# path everywhere, which is also what a differential test compares against, so
# this feature is never allowed to change the output bytes.
simd = []
# Measurement, not decoration. `examples/bench.rs` is what the SIMD and
# multi-core claims in the module docs are worth; `examples/repack_compare.rs`
# packs a real repository with this crate and with stock `git` and prints both
# sizes. Examples rather than `benches/` so that neither pulls in a benchmark
# harness dependency. This crate has to stay liftable (D21).
