# All cargo invocations for this spore go through this script so the host never
# needs Rust system deps, chromium, or chromiumoxide native libraries installed.
# Source is bind-mounted into /work, and the cargo registry + build target dirs
# live in named volumes (afhttp-cargo-home, afhttp-cargo-target) so successive
# runs share compilation caches.
#
# Usage:
#   tests/run-in-docker.sh cargo build --all-features
#   tests/run-in-docker.sh cargo test --workspace
#   tests/run-in-docker.sh bash -lc 'chromium --version'
#
# Helpers tests/build.sh and tests/test.sh dispatch here.
