Hello to all!
How can I define an interface for this method
suspend fun CoroutineScope.removeDuplicateTerminal(objectId: MutableList<Int>, token: String) = async { }

[antonis]

Hello. I don’t think an extension function can be extracted in an interface

[antonis]

What is your use case?

[Alexjok]

I use it in spring and want to make an autowired implementation through the interface.

[antonis]

It seems that I’m wrong. This looks valid

[antonis]

interface YourInterface {
suspend fun CoroutineScope.removeDuplicateTerminal(objectId: MutableList<Int>, token: String)
}

class YourClass: YourInterface {
override suspend fun CoroutineScope.removeDuplicateTerminal(objectId: MutableList<Int>, token: String) {
}
}

Thank! I hurried with the question 🙂
suspend fun CoroutineScope.removeDuplicateTerminal(objectId: MutableList<Int>, token: String): Deferred<Unit>

If your function starts a coroutine that doesn't need to return a result, you may consider returning a Job instead of Deferred<Unit>, replacing async with launch.
You can then job.join() to wait for the coroutine to complete its work.

Yes, you are right! Thank you
