}Expand description
A macro for quickly implementing crate::AsyncSendTryGetFut without capturing.
If you need capturing, you will have to manually capture what you want in a user-defined struct
and implement crate::AsyncSendTryGetFut for that struct.
For now this has to use Pin<Box<dyn Future>> due a compiler bug
(rust-lang/rust#100013).This will
change in a future release when this bug is fixed.
