pub enum RetainHandling {
    Send = 0,
    SendForNewSub = 1,
    DoNotSend = 2,
}

DoNotSend = 2

Never send retained messages

Trait Implementations

impl Clone for RetainHandling

fn clone(&self) -> RetainHandling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RetainHandling

impl Debug for RetainHandling

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

Formats the value using the given formatter.

impl Eq for RetainHandling

impl From<RetainHandling> for u8

fn from(value: RetainHandling) -> Self

Converts to this type from the input type.

impl PartialEq for RetainHandling

fn eq(&self, other: &RetainHandling) -> 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 RetainHandling

fn partial_cmp(&self, other: &RetainHandling) -> 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.

impl StructuralPartialEq for RetainHandling

impl TryFrom<u8> for RetainHandling

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
