Enum channel::message_queues::QueueStyle

pub enum QueueStyle {
    FIFO,
    LIFO,
    KLAST,
}

QueueStyle is an enum which can be used as a configuration option for PerValidatorQueue. Since the queue per key is going to be bounded, QueueStyle also determines the policy for dropping and retrieving messages.

With LIFO, oldest messages are dropped. With FIFO, newest messages are dropped. With KLAST, oldest messages are dropped, but remaining are retrieved in FIFO order

Variants

LIFO

KLAST
