Struct TopicFilterMap 

pub struct TopicFilterMap<V> {
    static_routes: BTreeMap<TopicFilter<Box<str>>, V>,
    wildcard_routes: BTreeMap<TopicFilter<Box<str>>, V>,
}

A map of topic filters to values, supporting MQTT wildcards.

Fields

static_routes: BTreeMap<TopicFilter<Box<str>>, V>

Static topic filters (without wildcards).

wildcard_routes: BTreeMap<TopicFilter<Box<str>>, V>

Wildcard topic filters (containing ‘+’ or ‘#’).

Implementations

impl<V> TopicFilterMap<V>

pub const fn new() -> Self

Creates a new, empty router.

pub fn iter(&self) -> impl Iterator<Item = (&TopicFilter<str>, &V)>

Returns an iterator over all topic filters and their associated values.

Note: The order of iteration is not guaranteed.

pub fn iter_mut(&mut self) -> impl Iterator<Item = (&TopicFilter<str>, &mut V)>

Returns a mutable iterator over all topic filters and their associated values.

Note: The order of iteration is not guaranteed.

pub fn get(&self, topic_filter: &TopicFilter<str>) -> Option<&V>

Returns a reference to the value for the given topic filter.

pub fn get_mut(&mut self, topic_filter: &TopicFilter<str>) -> Option<&mut V>

Returns a mutable reference to the value for the given topic filter.

pub fn insert( &mut self, topic_filter: TopicFilter<Box<str>>, value: V, ) -> Option<V>

Inserts a value for the given topic filter, returning the previous value if it existed.

pub fn get_or_insert_with( &mut self, topic_filter: &TopicFilter<str>, f: impl FnOnce() -> V, ) -> &mut V

Returns a mutable reference to the value for the given topic filter, inserting a new value if it does not exist.

pub fn remove(&mut self, topic_filter: &TopicFilter<str>) -> Option<V>

Removes the value for the given topic filter.

pub fn get_matches<'a>( &'a self, topic: &'a str, ) -> impl Iterator<Item = (&'a TopicFilter<str>, &'a V)> + 'a

Returns an iterator over the values matching the given topic.

pub fn get_matches_mut<'a>( &'a mut self, topic: &'a str, ) -> impl Iterator<Item = (&'a TopicFilter<str>, &'a mut V)> + 'a

Returns a mutable iterator over the values matching the given topic.
