Rappel: Compose Algorithms, Not Iterators - Google's Alternative to Ranges

Explore an innovative approach to composing operations on ranges in C++ with this conference talk from C++Now 2024. Delve into Rappel, Google's alternative to std::ranges, which proposes basing composition on a generalization of rather than . Learn how this method can potentially make composition safer, more efficient, and more flexible compared to C++20 ranges, while also offering monadic error handling. Examine the motivation behind Rappel, analyze its underlying semantic model, and compare it with std::ranges. Investigate the implementation details of Rappel and discover how it can be extended. Gain insights from Google engineers John Bandela and Chris Philip as they present this cutting-edge approach to algorithm composition in C++.
