}

The enumerated codes for the MQTT v5 properties.

The property code defines both the meaning of the value in the property (Correlation Data, Server Keep Alive) and the data type held by the property.

Implementations

impl PropertyCode

pub fn new(code: u32) -> Option<PropertyCode>

Tries to create a PropertyCode from the integer value.

pub fn property_type(&self) -> PropertyType

Get the property type from the code identifier.

pub fn type_of(&self) -> TypeId

Gets the any::TypeId that corresponds to the property type.

Trait Implementations

impl Clone for PropertyCode

fn clone(&self) -> PropertyCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyCode

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

Formats the value using the given formatter.

impl PartialEq for PropertyCode

fn eq(&self, other: &PropertyCode) -> 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 TryFrom<u32> for PropertyCode

fn try_from(code: u32) -> Result<PropertyCode, Error>

Try to convert from an integer property type to and enumeration value.

type Error = Error

The type returned in the event of a conversion error.

impl Copy for PropertyCode

impl Eq for PropertyCode

impl StructuralPartialEq for PropertyCode
