# Hot-reload image for the Rust tracking service. Used only by the
|
|
# `make dev` flow via docker-compose.dev.yml — production still uses
|
|
# tracking/Dockerfile.

|
# The container expects:
|
|
# - Source bind-mounted at /app
|
|
# - $CARGO_HOME / $CARGO_TARGET_DIR on named volumes so the registry
|
|
# and the compiled artifact cache survive container recreates AND
|
|
# are shared across worktrees.
|
|
#
|
|
# cargo-watch handles the watch loop: on any change under /app/src,
|
|
# it re-runs `cargo run`. Incremental compile against the warm
|
|
# target/ dir typically takes 2-10s for a single-file change.
