if you use actor.offer(message) (instead of actor.send(message) when the actor(capacity = Channel.UNLIMITED), is there locking involved?

[zak.taccardi]

my primary use case is that I want ensure delivery of the message, because the suspended actor.send(message) may get cancelled before delivery occurs. Think a ViewModel#onCleared() occurring which would cancel the scope in which actor.send(..) is called

locking or blocking?

locking

(I’m trying to write lock-free code)

[Dominaezzz]

I don't think kotlinx.coroutines uses locks ever.

[Dominaezzz]

Take that with a grain of salt of course.

I don't think that there is any locking with offer, an item will be added to lock-free queue

[gildor]

Also send to Unlimited channel should not work differently comparing to offer it would be mostly the same, because suspension point will return immediately
