# CI Overview
# -----------
#
# All pushes and PRs (including from forks) run:
#
#   - cargo build with the default cargo profile ("dev")
#   - cargo test
#   - cargo fmt
#   - clippy (with warnings denied)
#
# All workflow actions make use of our build container
# (`quay.io/influxdb/rust:ci`) to satisfy system dependencies, and is updated
# nightly.
#
# Cargo's build artefacts are cached to reduce the build time, see
# https://github.com/actions/cache for more info.
