Enum Delivery 

pub enum Delivery {
    AtLeastOnce,
    AtMostOnce,
}

How often a command may reach its handler.

Variants

AtLeastOnce

Redelivered until it is acknowledged, so handling it twice must be harmless.

AtMostOnce

Acknowledged before it is handled and never redelivered, so a handler that does not finish loses the command.

impl PartialEq for Delivery

fn eq(&self, other: &Delivery) -> bool

Tests for self and other values to be equal, and is used by ==.
