Struct TopicFilters 

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

Re-export common protocol types and payload handlers A collection of MQTT topic filters used in subscription and unsubscription operations.

Topic filters follow MQTT specification rules:

• May contain wildcards (+ for single-level, # for multi-level)
• Must be valid UTF-8 strings
• Follow specific formatting rules for wildcard placement

Examples

use mqute_codec::protocol::TopicFilters;

let filters = TopicFilters::new(vec!["sensors/temperature", "sensors/+/humidity"]);
assert_eq!(filters.len(), 2);

Implementations

impl TopicFilters

pub fn new<T: IntoIterator<Item: Into<String>>>(filters: T) -> Self

Creates a new TopicFilters instance from an iterator of topic filters.

Panics

Panics if:

• The iterator is empty (at least one topic filter is required)
• Any topic filter is invalid according to MQTT specification

pub fn len(&self) -> usize

Returns the number of topic filters in the TopicFilters instance.

Trait Implementations

impl AsRef<Vec<String>> for TopicFilters

fn as_ref(&self) -> &Vec<String>

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

impl Borrow<Vec<String>> for TopicFilters

fn borrow(&self) -> &Vec<String>

Immutably borrows from an owned value.

impl Clone for TopicFilters

fn clone(&self) -> TopicFilters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopicFilters

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

Formats the value using the given formatter.

impl From<TopicFilters> for Vec<String>

fn from(value: TopicFilters) -> Self

Converts to this type from the input type.

impl From<Vec<String>> for TopicFilters

fn from(value: Vec<String>) -> Self

Converts to this type from the input type.

impl FromIterator<String> for TopicFilters

fn from_iter<T: IntoIterator<Item = String>>(iter: T) -> Self

Creates a value from an iterator.

impl IntoIterator for TopicFilters

type Item = String

The type of the elements being iterated over.

type IntoIter = IntoIter<String>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for TopicFilters

fn eq(&self, other: &TopicFilters) -> 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.
