Implementations§

Source§

impl SubscriptionManager

Source

pub fn new() -> Self

Creates a new SubscriptionManager

Source

pub async fn add_subscription( &self, stream: String, symbol: String, sub_type: SubscriptionType, sender: Sender<Value>, ) -> Result<bool>

Adds a subscription to the manager.

If a subscription for the same stream already exists, increments the reference count instead of creating a duplicate subscription.

Returns true if a new subscription was created, false if an existing one was reused.

Source

pub async fn remove_subscription(&self, stream: &str) -> Result<bool>

Removes a subscription by stream name.

Only actually removes the subscription when the reference count reaches zero. Returns true if the subscription was fully removed (ref count hit zero).

Source

pub async fn get_subscription(&self, stream: &str) -> Option<Subscription>

Retrieves a subscription by stream name

Source

pub async fn has_subscription(&self, stream: &str) -> bool

Checks whether a subscription exists for the given stream

Source

pub async fn get_all_subscriptions(&self) -> Vec<Subscription>

Returns all registered subscriptions

Source

pub fn get_all_subscriptions_sync(&self) -> Vec<Subscription>

Returns all registered subscriptions synchronously (non-blocking)

Source

pub async fn get_subscriptions_by_symbol( &self, symbol: &str, ) -> Vec<Subscription>

Returns all subscriptions associated with a symbol

Source

pub fn active_count(&self) -> usize

Returns the number of active subscriptions

Source

pub async fn clear(&self)

Removes all subscriptions and clears indexes

Source

pub async fn send_to_stream(&self, stream: &str, message: Value) -> bool

Sends a message to subscribers of a specific stream

Source

pub async fn send_to_symbol(&self, symbol: &str, message: &Value) -> usize

Sends a message to all subscribers of a symbol

Source

pub async fn get_active_streams(&self) -> Vec<String>

Returns a list of all active stream names for resubscription
