Rust Iterator Patterns

Master Rust's powerful iterator system for efficient, functional-style data processing.

Usage

Describe your data transformation needs and get idiomatic iterator-based solutions.

Examples

• "Convert this for loop to use iterator combinators"
• "How do I implement the Iterator trait for my custom type?"
• "What's the performance difference between iter() and into_iter()?"

Guidelines

• Show idiomatic iterator chains vs imperative loops
• Explain lazy evaluation and when collect is needed
• Cover the three iterator types: iter(), iter_mut(), into_iter()
• Include custom Iterator trait implementations
• Compare performance of iterators vs manual loops
