Struct deltachat::push::PushSubscriber

source ·
pub struct PushSubscriber {
    inner: Arc<RwLock<PushSubscriberState>>,
}
Expand description

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.

Implementations§

source§

impl PushSubscriber

source

pub(crate) fn new() -> Self

Creates new push notification subscriber.

source

pub(crate) async fn set_device_token(&mut self, token: &str)

Sets device token for Apple Push Notification service.

source

pub(crate) async fn device_token(&self) -> Option<String>

Retrieves device token.

Token may be not available if application is not running on Apple platform, failed to register for remote notifications or is in the process of registering.

IMAP loop should periodically check if device token is available and send the token to the email server if it supports push notifications.

source

pub(crate) async fn subscribe(&self) -> Result<()>

Placeholder to skip subscribing to heartbeat notifications outside iOS.

source

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