Enum IdentifiedQoS 

pub enum IdentifiedQoS {
    AtMostOnce,
    AtLeastOnce(PacketIdentifier),
    ExactlyOnce(PacketIdentifier),
}

MQTT’s Quality of Service with special reference to the PUBLISH packet which contains a packet identifier if its Quality of Service is greater than 0.

Variants

AtMostOnce

Quality of Service Level 0. PUBLISH packets do not contain a packet identifier.

AtLeastOnce(PacketIdentifier)

Quality of Service Level 1. PUBLISH packets contain the included packet identifier.

ExactlyOnce(PacketIdentifier)

Quality of Service Level 2. PUBLISH packets contain the included packet identifier.

Implementations

impl IdentifiedQoS

pub const fn packet_identifier(&self) -> Option<PacketIdentifier>

Returns Some if QoS > 0 and therefore has to be identified, and None otherwise.

Trait Implementations

impl Clone for IdentifiedQoS

fn clone(&self) -> IdentifiedQoS

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IdentifiedQoS

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<IdentifiedQoS> for QoS

fn from(value: IdentifiedQoS) -> Self

Converts to this type from the input type.

impl PartialEq for IdentifiedQoS

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

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

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
