I'm working with https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.channels/-receive-channel/receive-catching.html which returns a ChannelResult. ChannelResult can be either succesful result or a failure result.

It seems like there are 2 types of failure results.
• isClosed is set to true
• isClosed is set to false and an exception is available from the https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.channels/-channel-result/exception-or-null.html function
My question is, for this operation, is it ever possible to get a failure result with isClosed set to false? Why would that ever happen?

[Joffrey]

From the KDoc of `receiveCatching`:

The result cannot be failed without being closed.

[Jacob]

Ahh so that means it will never happen?

[Joffrey]

Yes. ChannelResult is used in other APIs, but in the case of receiveCatching this case will never happen
