[Concurrency] Structured concurrency

[ktoso (Konrad 'ktoso' Malawski 🐟🏴‍☠️)]

Hey there,

@rsfinn

The second code section under Task handles includes the statement let meal = try await mealHandle() . I presume this was supposed to be let meal = try await mealHandle.get() instead?

Yes, you're right -- a handle has to be called on with get() to wait there.

I think we fixed this in the more recent revisions

@rsfinn

1. In the session I attended, I believe it was stated that a detached task doesn't begin running until .get() is called on its handle. On further reflection, that doesn't seem right to me. Is it?

Not sure what session you mean You’re right though — detached tasks (started by Task.runDetached) run right away, and the get is just what is where you suspend and wait for the result.

Hope this helps,

FYI: a more up to date proposal and discussion thread is: [Pitch #2] Structured Concurrency if you’d like to read up or ask more questions.
