Is there a coroutine/suspending network library out there yet?

Maybe you are looking for Ktor or Retrofit (Android)?

I think they are incubating kotlinx-io in ktor. I guess that is what you are looking for

not android. something like netty, but coroutine based.

ktor client and retrofit2

ktor looks like it just support HTTP requests... at least at a glance. handy but... not a network library.

You need to specify what you call "network library" then, because it's very broad otherwise.

hmm... networking? sockets (UDP, TCP etc). maybe a protocol or two implmented on top of those, maybe not..

anybody using Arrow's Either to wrap responses?
