Struct BdSeq 

pub struct BdSeq(/* private fields */);

The birth/death sequence number (bdSeq), incremented once per MQTT CONNECT (not per message) and persisted across restarts so the Host can correlate an NDEATH with its NBIRTH (tck-id-payloads-nbirth-bdseq*).

Implementations

impl BdSeq

pub const fn new(start: u8) -> Self

A counter starting at start.

pub const fn get(self) -> u8

The current value.

pub fn advance(&mut self)

Advance by one (wrapping 255 -> 0).

Trait Implementations

impl Clone for BdSeq

fn clone(&self) -> BdSeq

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BdSeq

impl Debug for BdSeq

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

Formats the value using the given formatter.

impl Default for BdSeq

fn default() -> BdSeq

Returns the “default value” for a type.

impl Eq for BdSeq

impl PartialEq for BdSeq

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