Rust deploy notes start before the binary is built.

Rust can produce tidy release artifacts, but a tidy artifact is not the same thing as a safe release. Rustjar deployment notes ask what configuration is baked in, what remains runtime-configurable, how migrations are sequenced, and what signal proves a rollout is healthy. The pattern is only useful when the rollback has a named owner and a tested path.

Practical Rust deployment also includes the boring details: musl-versus-glibc choices, image layers, startup probes, tracing spans, panic behavior, memory limits, and feature flag cleanup. The notes on this shelf favor repeatable release reviews over dramatic last-minute heroics.
