# Living Docs CLI — pinned dev/build image (Docker-always dev environment).
#
# The host is not assumed to have a Rust toolchain (rustfmt/clippy were missing on the
# host in earlier slices). This image pins the exact toolchain in cli/rust-toolchain.toml
# and adds a C toolchain so crates with native deps compile — the `cc` linker step that
# the old quality-gate image lacked.
#
# Never bakes the crate in: the Makefile mounts the repo at /work and runs `cargo ...`
# against it, so edits on the host are picked up without rebuilding the image.
#
# Build (from the repo root):
#   docker build -f Dockerfile.dev -t living-docs-dev .
#
# Run (see the `cli-*` Makefile targets for the full docker run invocation):
#   docker run --rm -v "$PWD:/work" -w /work living-docs-dev cargo test --manifest-path cli/Cargo.toml
