# Rust Systems & Services
Covers modern application-layer Rust (edition 2024): CLIs, web services, libraries. Not `no_std`/embedded.
## Working rules
- Preserve error variants in libraries and add operational context at application boundaries.
- Distinguish missing configuration from unreadable or invalid files before writing replacements.
- Keep blocking work off async workers, bound queues and spawned work, and define shutdown behavior.
- Trace exported interfaces before treating a change as internal; verify installed runtime capabilities.
- Do not mutate process-wide state in concurrent tests; exercise the real binary and relevant feature combinations.
## Unsafe Discipline
