Struct PacketId 

pub struct PacketId(NonZero<u16>);

MQTT Packet Identifier (§2.2.1).

Packet identifiers are non-zero u16 values assigned to QoS > 0 PUBLISH, SUBSCRIBE, and UNSUBSCRIBE packets.

Tuple Fields

0: NonZero<u16>

Implementations

impl PacketId

pub const MIN: PacketId

The smallest valid packet identifier (1).

pub const fn new(value: u16) -> Option<PacketId>

Creates a PacketId from a raw u16.

Returns None if the value is 0.

pub const fn get(self) -> u16

Returns the underlying u16 value (always >= 1).

pub const fn next(self) -> PacketId

Increments to the next packet ID, wrapping from 65535 back to 1.

Trait Implementations

impl Clone for PacketId

fn clone(&self) -> PacketId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PacketId

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

Formats the value using the given formatter.

impl Display for PacketId

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

Formats the value using the given formatter.

impl Hash for PacketId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PacketId

fn cmp(&self, other: &PacketId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PacketId

fn eq(&self, other: &PacketId) -> 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 PartialOrd for PacketId

fn partial_cmp(&self, other: &PacketId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
