Is there room for an MPSC?

[huntc]

Having spent some time on creating a PR for Embassy that introduces a non-alloc MPSC, there was a question posed as to whether the MPSC would be a better fit here.

The MPSC’s implementation is designed for single cores given its use of critical sections, but the API doesn’t restrict this. A multi core implementation could also be attained.

I realise that there is a MPMC here already, but perhaps the potential for optimisations of a single consumer may be of interest.

Here’s my Embassy PR: https://github.com/embassy-rs/embassy/pull/226, which remains open at this point.

Thanks!

I think this would be a good fit for heapless :) I have not had time to check the implementation, but it makes sense to have here.

Hi, did you decide if you wanted to look into adding an MPSC here?

My apologies for leaving this one open. I ultimately decided to implement it in embassy-rs where it now lives as an MPMC. Please feel free to close this if you’d like.
