rust-iterators

What problem does it solve?

Improve Rust data processing speed by replacing explicit loops with lazy iterator chains.

Core Features & Use Cases

• Lazy iteration patterns: map, filter, and fold avoid creating intermediate collections.
• Parallel processing with Rayon: scale data work across cores for large datasets.
• Custom iterators: implement size_hint and ExactSizeIterator for predictable performance.
• Memory-friendly processing: compose iterator adapters to minimize allocations during transformations.

Quick Start

Rewrite a for-loop that processes a collection into a chained iterator pattern that uses map and filter to produce the final result with no intermediate allocations.
