How can I support cancellation within a suspend function? If I don't use launch/async etc to launch anything

You either use cancellable suspending functions (yield, delay, etc) or check for isActive

Right, but if I'm just in a suspend function without any context, how should I do that? Maybe I misunderstand suspend functions but:

suspend fun sample() {
   // no isActive
}

I could launch something but I don't want to potentially change scopes/dispatchers

[elizarov]

coroutineContext.isActive

Wow, I had no idea such a variable existed. Thank you!
