CI.yml

# This file is based on the autogenerated one by maturin v1.7.8 with:
#
#    maturin generate-ci github
#
# Differences are:
# - removed x86, armv7, s390x, ppc64le targets from Linux
# - removed free-threaded wheels
# - removed musllinux
# - have separate linux-just-test and linux-min-versions-just-test jobs
# - add the `RUSTFLAGS: "-Dwarnings"` env variable
