Struct DeliveryAttempt 

pub struct DeliveryAttempt(/* private fields */);

How many times a delivery has been handed out and come back failed.

Implementations

impl DeliveryAttempt

pub const NONE: Self

A delivery that has not been attempted yet.

pub const fn value(self) -> u32

pub const fn next(self) -> Self

One more attempt, saturating rather than wrapping: a counter that wrapped would hand an exhausted delivery back to a host forever.
