Implementations

impl TopicFilter

pub fn new<S: Into<String>>(topic: S) -> Result<TopicFilter, TopicFilterError>

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

pub unsafe fn new_unchecked<S: Into<String>>(topic: S) -> TopicFilter

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

Methods from Deref<Target = TopicFilterRef>

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

Get a matcher
