itertools
A Rust library providing extra iterator adaptors, methods, free functions, and macros for more expressive iteration.
What is itertools?
Itertools is a Rust library that extends the standard library's iterator functionality with additional adaptors, methods, free functions, and macros. It solves the problem of verbose or repetitive iteration patterns by providing utilities for combining, transforming, and manipulating iterators more expressively and efficiently.
Rust developers working with collections, data processing, or algorithmic code who want more concise and powerful iterator patterns without sacrificing performance.
Developers choose Itertools because it offers zero-cost abstractions that make Rust code more readable and expressive while maintaining the language's performance guarantees, reducing boilerplate in common iteration tasks.
Overview
Extra iterator adaptors, iterator methods, free functions, and macros.
