When should one use async-await Vs withContext

[marstran]

Calling withContext is like doing await immediately on the Deferred from async. Use async if you want to do something else while waiting for the Deferred to complete.

Not exactly. A crash in the async block will cancel the parent scope.
withContext will only throw and will let you catch without an extra scope.

Makes sense , Thanks!

[rkeazor]

Ahhhhh

[rkeazor]

I see , thanks @louiscad!

[rkeazor]

So depending how you want your cancellation will be how you choose one from the other

@rkeazor Nope, I'll always using withContext if I need to change the dispatcher.
The only exception might be using flowOn to make a flow run on a specific dispatcher.

async is for parallelization in a coroutine.

cough concurrency not parallelism cough

[louiscad]

I see it as local parallelism. The issue is the connotation of these words that I want to avoid. Concurrency is more loaded of it IMHO.
