Enum and Pattern Matching in Rust

Enums in Rust define a type with multiple possible variants, each potentially holding data. Combined with `match`, they enable expressive and exhaustive control flow for handling different cases. Enums are ideal for representing states, options, or complex data with variant-specific logic.
