Struct mqtt::topic_filter::TopicFilterRef

#[repr(transparent)]
pub struct TopicFilterRef(_);

Reference to a TopicFilter

Implementations

impl TopicFilterRef

pub fn new<S: AsRef<str> + ?Sized>(
    topic: &S
) -> Result<&TopicFilterRef, TopicFilterError>

Creates a new topic filter from string Return error if it is not a valid topic filter

pub unsafe fn new_unchecked<S: AsRef<str> + ?Sized>(
    topic: &S
) -> &TopicFilterRef

Creates a new topic filter from string without validation

Safety

Topic filters’ syntax is defined in MQTT specification. Creating a filter from raw string may cause errors

pub fn get_matcher(&self) -> TopicFilterMatcher<'_>

Get a matcher
