How to Write a Flux Adaptor Using Coroutines

Todo:

• [ ] Fix date when finished.

$$ T_{over} = p \sum{x} $$

Target Audience

Professional C++ programmers and students/researchers who are familiar with C++.

Goal

1. Provide a resource that details how to write a quick adaptor using coroutines in Flux.

2. Provide working examples version locked on compiler explorer.

Outline

1. Quick intro to flux
   • Example of sequence oriented programming
   • Links to some talks and source
2. Basics of coyield
   • Explain how cpp implements coroutines, and what it actually means to use a coroutine
3. Very basics of writing an adaptor
   • We need a resumable function that yields elements in the sequence and returns when complete.
4. Writing a simple adaptor using coyield
   • Replicate the adaptor made by tcbrindle in his tutorial file
5. Writing a more complex adaptor using coyield
   • Write a permutations adaptor using coyield
6. Optional. Performance and usage tradeoffs
