Master Rust enums in this comprehensive tutorial! Learn how to define types with multiple variants, use pattern matching, and handle nullable values safely with the Option type.
📚 What You'll Learn:
• Creating basic enums with variants
• The match expression for exhaustive pattern matching
• Storing different data types inside enum variants
• Destructuring data from enum variants
• The built-in Option enum (Some and None)
• Safe handling of nullable values
💻 Code Examples:
1. Basic Enum:
enum Direction {
North,
South,
East,
West,
}
2. Enum with Data:
enum Message {
Quit,
Move { x: i32, y: i32 },
Write(String),
ChangeColor(i32, i32, i32),
}
3. Option Enum - returns Some(index) if found, None if not found
🔑 Key Concepts:
• enum - Define a type with fixed variants
• match - Handle each variant exhaustively
• Some(value) - Contains a value
• None - Represents absence of value
• Pattern matching extracts data from variants
