rust-pattern-matching

What problem does it solve?

Pattern matching in Rust is powerful but easy to misuse, leading to non-exhaustive matches, hidden edge cases, and fragile code. This guide helps developers reason about exhaustiveness, correct usage of Option/Result, and the full spectrum of pattern syntax to write safer, idiomatic Rust.

Core Features & Use Cases

• Exhaustiveness guidance: explains E0004 and how to avoid catch-all arms that mask future variants.
• Pattern syntax mastery: covers match guards, @ bindings, or-patterns, and binding modes.
• Anti-pattern detectors: identifies common pitfalls like manual panic in matches and nested pyramids.
• Learning and reference: serves as a reference for reviewing or learning Rust pattern matching in real-world code.
