Hi everyone! I'm trying to design a Kotlin API for ZeroMQ. My API currently resembles a lot to the `SendChannel`/`ReceiveChannel` API. I would like to implement some

onReceive: SelectClause1<Message>

and

onSend: SelectClause2<Message, SendSocket>

similar to the ones of the

Channel

API. Searching in this channel, I found: 1. some helpers to build select clauses https://gist.github.com/zach-klippenstein/fa4366388295282fa409c5085abada23 by @Zach Klippenstein (he/him) [MOD], however it seems to me that there are made to work with event callbacks, 2. a suggestion by @Matej Drobnič to use something like

async { mySuspendFunction() }.onAwait

, however I can't seem to build a proper

SelectClause1

with this. As ZeroMQ uses a polling mechanism, I don't quite figure out how to use either of these solutions. Also, the

AbstractChannel

code is quite overwhelming. Is there a paper/article discussing the possible

SelectClause

implementations somewhere? Do anyone of you have some hints or advices to give me? Thanks in advance!

Alternatively, you could consider using a Channel directly in your API or the API's implementation?
