Distinguishing coroutines and fibers

by Nat Goodspeed and Oliver Kowalke

Excerpt:

The purpose of this paper is to foreshadow a forthcoming proposal to introduce fibers to the C++ standard library; to briefly describe the features in the proposed fiber library; and to contrast it with the coroutine library proposed in N39856.

It is hoped that this comparison will help to clarify the feature set of the proposed coroutine library. Certain features properly belong in the coroutine library; other conceptually-related features more properly belong in the fiber library.
