Struct LiveCapabilitySubscription

Source

pub struct LiveCapabilitySubscription<T> {
    pub initial_results: Vec<T>,
    /* private fields */
}

Expand description

A capability-scoped subscription to a live query that streams updates for records within a specific capability.

Similar to LiveQuerySubscription, but only receives updates for records within the specified capability. This provides more granular control over subscription scope.

Implementations§

Source §

impl<T> LiveCapabilitySubscription<T>
where T: DeserializeOwned + Send + Sync + 'static,

Source

pub fn set_predicate<F>(&mut self, predicate: F)
where F: Fn(&T) -> bool + Send + Sync + 'static,

Source

pub async fn next(&mut self) -> Option<Vec<T>>

Waits for the next change event within this capability and returns the updated query results.

Similar to LiveQuerySubscription::next(), but only responds to changes within the scoped capability.
