I want to replace the `GlobalScope` in `GlobalScope async `but without using `coroutineScope ` I mean I want to write `x async ` how do I do that what should `x` be to make it the equivalant of doing `coroutineScope ` is this possible the reason I ask is because it requires a lot of reworking to use `coroutineScope ` for this section of code

I want to replace the `GlobalScope` in `GlobalScope async `b kotlinlang #coroutines

# coroutines

I want to replace the

GlobalScope

in `GlobalScope.async { }`but without using

coroutineScope { }

- I mean I want to write

x.async{ }

- how do I do that? what should

be? to make it the equivalant of doing

coroutineScope { }

? is this possible? the reason I ask is because it requires a lot of reworking to use

coroutineScope { }

for this section of code

I want to replace the
GlobalScope
in `GlobalScope.async { }`but without using
coroutineScope { }

What do you mean? coroutineScope has very different semantics and use case

I mean I want to write
x.async{ }
- how do I do that? what should
x
be?

It should be some CoroutineScope.

how do I make a CoroutineScope without the

coroutineScope { }

02/04/2019, 12:06 PM

implement CoroutineScope

02/04/2019, 12:07 PM

ok I'll look into how to implement CoroutineScope, thanks

02/04/2019, 12:07 PM

Usually coroutine scope is just some class that has lifecycle: UI component, connection etc

What is your use case? Where exactly you want call

x.async{}

my current code is like this

val f: Deferred<Status> = abc.deferredClose ?: let {
                val g = GlobalScope.async { foo(abc) } 
                abc.deferredClose = g
                g
            }

the GlobalScope is there because I'm upgrading from older coroutines and had to do something temporarily to get it to compile

If it’s migration step than GlobalScope is just fine

02/04/2019, 12:22 PM

ok I'll leave it as is then for now, thanks

02/04/2019, 12:22 PM

If you want migrate to StructuredConcurrency, class that contains

should implement CoroutineScope and you should control it lifecycle (otherwise you leaking coroutine)

02/04/2019, 12:24 PM

ok, I'll make note of this and will do that at a future date
