Struct SubTopic 

pub struct SubTopic(/* private fields */);

Topic pattern used in subscribe/unsubscribe packet.

Implementations

impl SubTopic

pub fn new(topic: &str) -> Result<Self, TopicError>

Create a new subscription topic.

Errors

Returns error if topic pattern is invalid.

pub fn bytes(&self) -> usize

Get byte length in packet.

Trait Implementations

impl AsRef<str> for SubTopic

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SubTopic

fn clone(&self) -> SubTopic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubTopic

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

Formats the value using the given formatter.

impl DecodePacket for SubTopic

fn decode(ba: &mut ByteArray<'_>) -> Result<Self, DecodeError>

Decode byte array into a mqtt packet.

impl Default for SubTopic

fn default() -> SubTopic

Returns the “default value” for a type.

impl EncodePacket for SubTopic

fn encode(&self, buf: &mut Vec<u8>) -> Result<usize, EncodeError>

Encode packets into byte array.

impl Hash for SubTopic

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SubTopic

fn cmp(&self, other: &SubTopic) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SubTopic

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

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