Hello everyone, when calling ReceiveChannel<T>::receiveCatching i get an object of type ChannelResult<ChannelResult<T>> back. But when i call ReceiveChannel<T>::receive i get an object of type T. Is this a bug or did i miss something in the API? Thanks in advance!

receive

will throw an exception if the channel is closed.

receiveCatching

doesn't throw, it returns you a failed

ChannelResult

instead.

Yes, but as far as i understood the documentation of receiveCatching it should return a ChannelResult<T>, not a ChannelResult<ChannelResult<T>>

Oops, I completely skipped that part of your question... Yes it should not do that as far as I can tell

Can you post the body of the particular function (plus context)? I used those apis and cannot see the same issue

If you make heavy use of smart casting and generics, you may have accidentally specified a generic type to be

ChannelResult<T>

instead of

T

. Create a temporary variable

val tempVariable = {yourChannelVariable}

and set it to the channel in question, then have the IDE add the explicit type. It’s likely that your channel’s type is

ChannelResult<T>

and not

T

Yes, i just created a minimum example: https://github.com/FelixEngl/ReceiveChannelStangeBehaviourME/tree/main
