Enum TopicReference 

pub enum TopicReference<'t> {
    Name(TopicName<'t>),
    Alias(u16),
    Mapping(TopicName<'t>, u16),
}

The options for specifying which topic to publish to. Topic aliases only last for the duration of a single network connection and not necessarily until the session end.

Topic aliases must not be 0

Variants

Name(TopicName<'t>)

Publish to the inner topic name without creating an alias.

Alias(u16)

Publish to an already mapped topic alias. The alias must have been defined earlier in the network connection.

Mapping(TopicName<'t>, u16)

Create a new topic alias or replace an existing topic alias. The alias lasts until the end of the network connection.

Implementations

impl<'t> TopicReference<'t>

pub fn as_borrowed(&'t self) -> Self

Delegates to crate::Bytes::as_borrowed.

Trait Implementations

impl<'t> Clone for TopicReference<'t>

fn clone(&self) -> TopicReference<'t>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'t> Debug for TopicReference<'t>

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

Formats the value using the given formatter.

impl<'t> PartialEq for TopicReference<'t>

fn eq(&self, other: &TopicReference<'t>) -> 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.
