Pattern Matching

Overview

Pattern matching in Rust is a powerful feature used to destructure and match values.

Topics

• match Expressions
• if let and while let
• Destructuring Structs, Enums, and Tuples

Examples

let number = 7;

match number {
    1 => println!("One"),
    2 | 3 | 5 | 7 => println!("Prime"),
    _ => println!("Other"),
}

if let Some(x) = Some(10) {
    println!("Matched: {}", x);
}

while let Some(x) = Some(5) {
    println!("Looping with: {}", x);
    break;
}
