Rappel: Compose Algorithms, Not Iterators - Google's Alternative to Ranges - John Bandela and Chris Philip - C++Now 2024
---

Is std::ranges the best way to compose operations on ranges?

What if instead of basing composition on a generalization of ＜iterator＞, we instead based composition on a generalization of ＜algorithm＞?

What if doing this enabled us to make composition safer, more efficient, and more flexible compared to C++20 ranges?

And what if we got monadic error handling as a bonus?

Join us for an introduction to Rappel - a library implementing this approach!

We will begin by examining the motivation for Rappel, including an in-depth analysis of its underlying semantic model, which differs from std::ranges.

We will explore the tradeoffs between this model and std::ranges.

Finally, we will delve into the implementation of Rappel and discuss how it can be extended.
