Struct SessionTopicMap 

pub struct SessionTopicMap<T, TX> { /* private fields */ }

Map of generic topics to session ids and of session ids to a channel sender.

Implementations

impl<T, TX> SessionTopicMap<T, TX>

where T: Clone + Hash + Eq,

pub fn insert_with_topic(&mut self, session_id: u64, topic: T, tx: TX)

Insert a session id with their topic and tx channel.

pub fn drop(&mut self, session_id: u64) -> bool

Drop a session from all mappings.

Returns true if the session existed and was dropped, otherwise returns false when the session was known

pub fn topic(&self, session_id: u64) -> Option<&T>

Get the topic for a session id.

Returns None of the session id was not known.

pub fn sessions(&self, topic: &T) -> HashSet<u64>

Get ids for all sessions associated with the given topic.

pub fn sender(&self, session_id: u64) -> Option<&TX>

Get a reference to a session sender.

pub fn sender_mut(&mut self, session_id: u64) -> Option<&mut TX>

Get a mutable reference to a session sender.
