Struct Subscription 

pub struct Subscription { /* private fields */ }

A handle to a subscription created by GPUI. When dropped, the subscription is cancelled and the callback will no longer be invoked.

Implementations

impl Subscription

pub fn new(unsubscribe: impl FnOnce() + 'static) -> Subscription

Creates a new subscription with a callback that gets invoked when this subscription is dropped.

pub fn detach(self)

Detaches the subscription from this handle. The callback will continue to be invoked until the entities it has been subscribed to are dropped

pub fn join( subscription_a: Subscription, subscription_b: Subscription, ) -> Subscription

Joins two subscriptions into a single subscription. Detach will detach both interior subscriptions.
