How does pattern matching work in Rust with match expressions?

Pattern matching in Rust: • Exhaustive matching required • Destructures data types • Guards with if conditions • Wildcard _ for catch-all • Must handle all cases Example: enum Coin { Penny, Nickel, Dime, Quarter } fn value_in_cents(coin: Coin) -> u8 { match coin { Coin::Penny => 1, Coin::Nickel => 5, Coin::Dime => 10, Coin::Quarter => 25, } }
