hi, if I'm given a scope called bigScope how can I create a scope smallScope that will be canceled when bigScope is cancelled?

[octylFractal]

CoroutineScope(Job(bigScope.coroutineContext[Job]))?

[Mikołaj Kąkol]

val smallScope = CoroutineScope(Dispatchers.Main + bigScope.coroutineContext)

like that?

[Mikołaj Kąkol]

is Job necessary?

[Mikołaj Kąkol]

val smallScope = CoroutineScope(Dispatchers.Main + Job(bigScope.coroutineContext[Job]))

compiles too, could you point a difference?

[octylFractal]

yes, the Job(parent: Job) constructor means structured concurrency

[octylFractal]

basically it declares that smallScope is a child of bigScope

[octylFractal]

rather than the same Job as bigScope

[Mikołaj Kąkol]

great, thankyou 🙂
