Chapter 11: Traits, Generics, and Lifetimes

In this chapter, we explore three fundamental features of Rust that enable code reuse, abstraction, and memory safety: traits, generics, and lifetimes. These concepts are closely intertwined in Rust, allowing you to write flexible, efficient, and safe code while maintaining strict type safety.

Traits define shared behavior, acting as interfaces or contracts. Generics enable code to work with different data types seamlessly. Lifetimes ensure that references are valid and prevent dangling pointers, playing a critical role in Rust's memory safety without a garbage collector.

Understanding traits, generics, and lifetimes is crucial for mastering Rust, but they can be challenging concepts, especially since many other programming languages do not have direct equivalents. In this chapter, we'll delve deeply into these topics, explaining how they interact and how to use them effectively in your Rust programs.
