One para explanation of the feature.
Why are we doing this? What use cases does it support? What is the expected outcome?
How does this affect public Rayon APIs? If this is purely an implementation detail, it's ok to note that it doesn't affect Rayon users very much.
Describe at a high-level details of the implementation. This doesn't
have to be super detailed; e.g., if we are adding a new
ParallelIterator API, it it probably fine to leave some of this up
to the Rayon PR. It is also fine to open a PR on the Rayon repository
and link it to this RFC (and vice versa).
- Why is this design the best in the space of possible designs?
- What other designs have been considered and what is the rationale for not choosing them?
- What is the impact of not doing this?
Anything left unresolved that we'll need to work out and evaluation during implementation? Feel free to leave this section blank if you can't think of anything. "
