# delta-rs 1.6.1 switched delta-kernel from the crates.io release (buoyant_kernel
# 0.22.2 in 1.6.0) to the buoyant-data delta-kernel-rs fork pinned to a branch
# commit, so these two move out of CRATES into GIT_CRATES (fetched + extracted).
# The eclass's generated [patch] does NOT redirect a branch-pinned + package-
# renamed git dep under the maturin/offline build, so src_prepare also repoints
# the workspace dep at the extracted tree. verified 2026-06-25.

# 1.6.0 is wheel-only on PyPI (no sdist), so source comes from the
# delta-io/delta-rs monorepo at the python-v${PV} tag. The maturin
# project lives in python/; its Cargo.lock is NOT committed upstream
# (gitignored) — CRATES above was generated from `cargo generate-lockfile`
# (workspace: crates/* + python). See the deltalake memory for the recipe.
