Struct Control 

pub struct Control { /* private fields */ }

A cloneable handle to a subscriber’s delivery preferences.

This updates the same subscription as the owning Subscriber without borrowing its read cursor, so callers can change delivery priority, the max age budget, or group bounds while another task is waiting for groups.

Implementations

impl Control

pub fn subscription(&self) -> Subscription

This subscriber’s current preferences.

pub fn update(&self, subscription: Subscription) -> Result<()>

Replace this subscriber’s preferences, updating the producer’s aggregate.

Returns Error::Closed if the track already ended; the update is meaningless at that point and can usually be ignored.

Trait Implementations

impl Clone for Control

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
