Struct FinalPoll

#[non_exhaustive]
pub struct FinalPoll<O, E> { /* private fields */ }

Result of the final polling attempt made by a waiter.

Waiters make several requests (“polls”) to the remote service, and this struct holds the result of the final poll attempt that was made by the waiter so that it can be inspected.
