Rust Generics Tutorial - Write Once, Use With Any Type | Rust for Beginners #24

Learn Rust generics and write flexible, reusable code that works with any data type! In this lesson, you'll master: - Generic Functions - Write functions that work with multiple types - Generic Structs - Create data structures that hold any type - Trait Bounds - Constrain generics to types with specific behavior Generics are essential for writing DRY (Don't Repeat Yourself) code in Rust. Instead of writing separate functions for integers, floats, and strings, you write one generic function that handles them all - with zero runtime cost! TOPICS COVERED: 00:00 - Introduction to Generics 00:30 - Generic Functions with Type Parameters 02:15 - Generic Structs (Point example) 04:00 - Trait Bounds (Display, Debug) 05:45 - The where Clause for Complex Bounds 07:00 - Summary and Next Steps KEY CONCEPTS: - fn print_value of T where T implements Debug - struct Point of T with x and y fields - Trait bounds using colon syntax - Multiple bounds with plus sign - The where clause for cleaner code This is part of our Rust Programming for Beginners series!
