Thanks for the contribution, however payjoin-directory is being deprecated in favor of the unified payjoin-service. We may revisit whether tokio-listener is worth adding as a dependency there, but I think a simple serde::Deserializer implementation for the port would be sufficient. I'm updating #941 now to make this clearer.

maybe factor out a tower_http OHTTP gateway middleware

@spacebear21 Can I take up this one now if it is on priority, or it should be worked after the merge of payjoin-directory and ohttp-relay?

Also, are there any priority issues you’d recommend I pick up?

I just ported this change to #941 and credited you as co-author on that commit 776943f. I'd appreciate a review on that PR and it may help you if you'd like to work on follow-up issues related to the directory/relay infrastructure!

Other than that there is a new tracking issue for FFI related gaps that could be good first issues #1264
