Rust Enums & Pattern Matching Explained | Rust Programming Tutorial | Learn Rust Step by Step

Описание: Welcome back to The Thinking Terminal!
In this video, we break down one of Rust’s most powerful features — Enums and Pattern Matching.

If you're learning Rust, understanding enums is a game-changer. They help you write cleaner, safer, more expressive code — and they replace many problems that other languages solve with error-prone strings or null values.

🔥 In This Video, You Will Learn:
✅ What Enums Are in Rust
Why use enums instead of strings
How enums restrict values safely with example

✅ Enums with Data (Advanced Variants)
Struct-like variants
Tuple-like variants
Storing mixed data inside one enum
Real examples using a Message enum

✅ Adding Methods to Enums
Using impl blocks
Calling methods with different variants

✅ Pattern Matching with match
Matching all variants
Extracting data from patterns
Writing custom logic for each variant
Handling all cases safely (exhaustive matching)
The _ wildcard pattern

✅ The Option Enum — Rust’s Replacement for Null
Understanding Some(value) and None
Returning optional values
Using match to handle both cases

✅ if let — A Simpler Way to Match One Pattern
Cleaner syntax for single-case matching
When to use if let instead of match

✅ Pattern Guards (Advanced)
Adding conditions to a match arm
Nested and complex patterns
Real example with a Temperature enum

🧠 By the end of this video, you will be able to:

✔ Define enums of any complexity
✔ Attach methods to enums
✔ Use pattern matching confidently
✔ Replace nulls with Option
✔ Write cleaner & safer Rust code
