Chapter 13: Mastering Iterators in Rust

Iterators are at the core of Rust’s design for safely and efficiently traversing and transforming data. By focusing on what to do with each element rather than how to retrieve it, iterators eliminate the need for manual index bookkeeping (common in C). In this chapter, we will examine how to use built-in iterators, craft your own, and tap into Rust’s powerful abstractions without compromising performance.
