Struct mqtt::topic_name::TopicNameRef

pub struct TopicNameRef(_);

Reference to a topic name

Methods

impl TopicNameRef

pub fn new<S: AsRef<str> + ?Sized>(
    topic_name: &S
) -> Result<&TopicNameRef, TopicNameError>

Creates a new topic name from string Return error if the string is not a valid topic name

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

Creates a new topic name from string without validation

Safety

Topic names' syntax is defined in MQTT specification. Creating a name from raw string may cause errors

pub fn is_server_specific(&self) -> bool

Check if this topic name is only for server.

Topic names that beginning with a '$' character are reserved for servers
