Returning a value produced in Kotlin coroutine

Question

I am trying to return a value generated from coroutine

fun nonSuspending (): MyType {
    launch(CommonPool) {
        suspendingFunctionThatReturnsMyValue()
    }
    //Do something to get the value out of coroutine context
    return somehowGetMyValue
}

I have come up with the following solution (not very safe!):

fun nonSuspending (): MyType {
    val deferred = async(CommonPool) {
        suspendingFunctionThatReturnsMyValue()
    }
    while (deferred.isActive) Thread.sleep(1)
    return deferred.getCompleted()
}

I also thought about using event bus, but is there a more elegant solution to this problem?

Thanks in advance.

Answer 1

You can do

val result = runBlocking(CommonPool) {
    suspendingFunctionThatReturnsMyValue()
}

to block until the result is available.
