Rust Optimise Best Practices

Performance optimization guide for Rust applications. Contains 42 rules across 8 categories, prioritized by impact from critical (memory allocation, ownership) to incremental (micro-optimizations).

When to Apply

• Optimizing Rust code for performance or reducing allocations
• Choosing data structures for optimal algorithmic complexity
• Working with iterators to avoid unnecessary intermediate allocations
• Writing async code with Tokio or other runtimes
• Profiling hot paths and eliminating performance bottlenecks
• Reviewing code for performance anti-patterns
