anybody know if there's a way to get a kotlinx io `Source` from a `ByteReadChannel`?

found <https://youtrack.jetbrains.com/issue/KTOR-6487> but it was closed

Seems impossible. You could go the other way, though.

The only option I see would be to use `runBlocking` which is bad because the `Source` could already be inside a coroutine on an IO thread. And you're not supposed to do that.

The API contract of `RawSource.read` is that it will obtain at least a single byte, and that requires blocking which an async mechanism just can't fulfill.

Okio has a `Pipe` which is closer to what's needed here

it doesn't even register as strange with me anymore. i just know your flavor of english will contain these references

I could see <http://kotlinx.io|kotlinx.io> getting some sort of suspension-based, pipe-like type in the future so that one coroutine could be consuming a bunch of data sources (like http/2 streams) and writing them into these pipes for individual consumers to suspend and wait for chunks as segments

although not sure how you make all the nice Source APIs work such that when there's a byte underflow they suspend. seems like maybe you'd be able to require so many bytes in a Buffer or something and then you get to non-blocking read from that until you decide to wait or hit EOF and have to wait
