+Use the unversioned `stable` channel for Rust builds and tests. Use the
+unversioned `nightly` channel for Rust formatting. Do not select numbered
+compiler versions or dated nightly versions in local tasks, CI, or container
+builds. Rust container images must follow the stable release with a floating
+distribution tag.
