Name:           rust-libdeflate-sys
Version:        1.23.0
Release:        %autorelease
Summary:        Bindings to libdeflate for DEFLATE

License:        Apache-2.0
URL:            https://crates.io/crates/libdeflate-sys
Source:         %{crates_source}
# Manually created patch for downstream crate metadata changes
# * Make the dependency on crate(pkg-config) non-optional instead of associating
#   it with the “dynamic” feature, since we patch the crate to always link
#   dynamically with the system libdeflate, regardless of the selected features.
Patch:          libdeflate-sys-fix-metadata.diff

BuildRequires:  cargo-rpm-macros >= 24
BuildRequires:  pkgconfig(libdeflate)

# The above two sed-patches effectively revert “Dynamic Linking Constraints”,
# https://github.com/adamkewley/libdeflater/pull/32. Using sed instead of a
# patch file keeps us from having to update the patch every time the version
# number changes.
