Struct deltachat::push::PushSubscriber

pub struct PushSubscriber {
    inner: Arc<RwLock<PushSubscriberState>>,
}

Manages subscription to Apple Push Notification services.

This structure is created by account manager and is shared between accounts. To enable notifications, application should request the device token as described in https://developer.apple.com/documentation/usernotifications/registering-your-app-with-apns and give it to the account manager, which will forward the token in this structure.

Each account (context) can then retrieve device token from this structure and give it to the email server. If email server does not support push notifications, account can call subscribe method to register device token with the heartbeat notification provider server as a fallback.

pub(crate) async fn subscribe(&self, _context: &Context) -> Result<()>

Placeholder to skip subscribing to heartbeat notifications outside iOS.

pub(crate) async fn heartbeat_subscribed(&self) -> bool
