# Rust stack overlay fragment.
#
# Layer this on top of huskies-project-base to produce a project container
# with a full Rust toolchain, rust-analyzer, and cargo-nextest.
#
# Build the combined image:
#   (echo "FROM huskies-project-base"; \
#    cat docker/stacks/rust/Dockerfile.fragment) | \
#   docker build -t huskies-project-rust -
#
# Adding a new stack: create docker/stacks/<name>/Dockerfile.fragment and
# docker/stacks/<name>/markers — no changes to orchestration code required.
