- Inline function calls in Rust async code often don't add significant overhead.
- Extracting logic into separate functions improves readability and maintainability.
- The compiler can optimize extracted functions to produce the same assembly as inlined code.
- Function call overhead is negligible compared to I/O, locks, or allocations.
- Performance concerns should be validated with benchmarks and profiling.
- Cognitive load and maintainability costs outweigh minor runtime optimizations.
- Rust's design philosophy encourages clean abstractions and trusting the optimizer.
- Well-named functions improve testability and system understanding.
- Prioritize readability and maintainability over micro-optimizations.
- Future AI agents will benefit from clear, well-structured code.
