Add `BlockAwait` trait #2803

Closed hwittenborn closed 10 months ago

hwittenborn commented 10 months ago

This change adds in a trait called BlockAwait, which functions like futures::executor::block_on, but allows for a chaining style similar to .await syntax.

I wasn't positive if this would be wanted, but considering how simple it was I decided I'd just go ahead and make it.

I also wasn't completely sure on how I should limit the trait to only be implemented on Future types (and possibly how to prevent it's implementation from being overridden), but I'm open to feedback in the area if my implementation isn't the best.

Users are free to define such helpers themselves, but I would prefer that this not be provided as part of the futures crate. See https://github.com/smol-rs/async-task/issues/16#issuecomment-1066674511 and subsequent comments for more.

Thanks anyway for the PR!
