withTimeoutOrNull
suspend fun <T> withTimeoutOrNull(
time: Int,
block: suspend CoroutineScope.() -> T
): T? (source)Runs a given suspending block of code inside a coroutine with a specified timeout and returns
null if this timeout was exceeded.
The code that is executing inside the block is cancelled on timeout and the active or next invocation of
cancellable suspending function inside the block throws TimeoutCancellationException.
Even if the code in the block suppresses TimeoutCancellationException, this
invocation of withTimeoutOrNull still returns null.
The sibling function that throws exception on timeout is withTimeout. Note, that timeout action can be specified for select invocation with onTimeout clause.
This function delegates to Delay.invokeOnTimeout if the context CoroutineDispatcher implements Delay interface, otherwise it tracks time using a built-in single-threaded scheduled executor service.
Parameters
time - timeout time in milliseconds.
