Rust Tutorial: Pattern Matching
master match expressions, destructuring, guards, and the @ binding operator.
Pattern matching
Rust's `match` is one of its most powerful features. It is exhaustive, expressive, and safe.
Patterns appear in many places: `let`, `if let`, `while let`, `for`, function parameters, and `match`.
What you'll learn in this Rust pattern matching tutorial
This interactive Rust tutorial has 8 hands-on exercises. Estimated time: 20 minutes.
- Basic match — `match` compares a value against patterns and runs the first matching arm.
- Matching ranges — Use `..=` to match a range of values in a pattern.
- Multiple patterns with | — Use `|` to match multiple patterns in one arm.
- Destructuring tuples — Match and destructure a tuple in one go.
- Destructuring structs — Match fields of a struct by name.
- Match guards — Add an `if` condition to a pattern arm — a guard:
- @ bindings — Bind a name to the matched value while also testing a pattern:
- while let — `while let` loops as long as a pattern matches.
