Implementations

impl Sync

pub fn subscriptions( &self ) -> impl '_ + Deref<Target = SetArc<SyncSubscription>>

Gets temporary access to the set of currently registered subscriptions.

A (read) lock is held until the return value is dropped: this means that neither Self::register_subscription() nor SyncSubscription::cancel() can make progress until this read lock is released.

pub fn register_subscription<Q>( &self, query: Q, query_args: Option<QueryArguments> ) -> Result<Arc<SyncSubscription>, DittoError>where Q: TryInto<Query, Error = DittoError>,

Run the provided query on the device of connected peers and send the results of the query back to the local peer’s data store.

The returned SyncSubscription object must be kept in scope for as long as you want to keep receiving updates.

Use placeholders to incorporate values from the optional query_args parameter into the query. The keys of the QueryArguments object must match the placeholders used within the query. You cannot use placeholders in the FROM clause.
