Is there a way to use a select expression with something that's not a channel?

Yes! You can select on anything (using the right abstraction)!

What about

ByteReadChannel

do you want to select?

Well it's a custom type I'm reading

But it gives an error,

Suspend functions can only be called within a coroutine body

Looking at

onReceive()

It seems I need a

SelectClauseX

?

You'll basically have to wrap the call in

async

and select using the

onAwait

.

You could also implement your own select clause but iirc it's experimental and there little docs about writing them.
