Episode notes
Let The Compiler Guard Memory
- Rely on Rust to eliminate memory and ownership bugs so tests focus on logic and safety-critical behavior.
- Treat every test as an investment and prioritize verifying domain-specific correctness over low-level leaks.
Compiler Catches Long-Range Coupling
- Rust's non-exhaustive coverage errors catch long-range coupling across components at compile time.
- This reduces runtime surprises when changing shared data structures in a highly coupled robotics stack.
Avoid Panics In Field Software
- Enforce safe idioms via culture, clippy, and code review; avoid unwraps and panics in robot processes.
- Prefer explicit error handling to prevent unexpected process panics in the field.
