Iterators and Ranges - Comparing C++ to D to Rust

Explore the differences between iterator and range models in C++, D, and Rust in this comprehensive conference talk from CppNow 2021. Delve into the STL iterator abstraction in C++ and compare it to alternative approaches in D and Rust. Examine the strengths and weaknesses of each language's model through implementations of common operations like map, filter, and find_if. Gain insights into the nuances of iterator-pair models versus other iteration paradigms used in languages such as Python and Java. Learn from detailed code examples and analysis of how these different approaches impact language design and usage.
