Is there a less try / catch oriented way of accessing the result of async? Thinking of something similar to Result

[Marko Mitic]

something like tryAwait?

[aerb]

What is that? I can’t find any references to it

[Marko Mitic]

that's hypothetical example 😄

[aerb]

-_-

[Marko Mitic]

I can't find functions like that either but it's quite easy to write, though

[aerb]

that has been my approach - was curious if there was an endorsed way

I would argue deferred.runCatching { await() } is probably more readable anyway, since it’s super obvious what it does and doesn’t require learning more API on Deferred.

An async will still cancel its scope though, unles its a supervisor one, or has no job (like GlobalScope)

[Marko Mitic]

Yeah, I find that behavior strange

[Marko Mitic]

On one side, exception is lost unless you call await() but even catching it doesn't stop cancellation of parent job.

It's simple: either you catch it around the local coroutineScope { … }, or you catch it inside the async block. If you don't do parallelization, you most probably don't need async at all though, only suspending function + try catch.
