pub(super) fn new(max: u16) -> Self

Trait Implementations

impl TopicAliasTable for OutboundAliases

fn decide(&self, topic: &Topic) -> AliasDecision

Decides the alias for topic without mutating state. A New decision must only be recorded once the packet reaches the wire (see confirm), so a publish dropped before sending leaves no phantom mapping.

fn confirm(&mut self, topic: &Topic, alias: NonZeroU16)

Records a New alias after its establishing PUBLISH has been written.
