Enum TimerKind 

pub enum TimerKind {
    PingreqSend,
    PingreqRecv,
    PingrespRecv,
}

Represents different types of MQTT timers

This enum defines the different kinds of timers used in MQTT protocol operations. Each timer serves a specific purpose in maintaining connection health and protocol compliance.

Variants

PingreqSend

Timer for sending PINGREQ packets

This timer is used by MQTT clients to schedule periodic PINGREQ packets to keep the connection alive. The interval is typically determined by the keep-alive value negotiated during connection establishment.

PingreqRecv

Timer for receiving PINGREQ packets

This timer is used by MQTT servers (brokers) to detect when a client has not sent a PINGREQ packet within the expected timeframe, indicating a potentially disconnected or unresponsive client.

PingrespRecv

Timer for receiving PINGRESP packets

This timer is used by MQTT clients to detect when a server has not responded to a PINGREQ packet with a PINGRESP within the expected timeframe, indicating a potentially disconnected or unresponsive server.

Trait Implementations

impl Clone for TimerKind

fn clone(&self) -> TimerKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimerKind

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

Formats the value using the given formatter.

impl PartialEq for TimerKind

fn eq(&self, other: &TimerKind) -> 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.

impl Serialize for TimerKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
