source§fn can_subscribe(&mut self, topic_hash: &TopicHash) -> bool
fn can_subscribe(&mut self, topic_hash: &TopicHash) -> bool
Returns true iff the topic is of interest and we can subscribe to it.
source§fn filter_incoming_subscriptions<'a>(
&mut self,
subscriptions: &'a [Subscription],
currently_subscribed_topics: &BTreeSet<TopicHash>,
) -> Result<HashSet<&'a Subscription>, String>
fn filter_incoming_subscriptions<'a>( &mut self, subscriptions: &'a [Subscription], currently_subscribed_topics: &BTreeSet<TopicHash>, ) -> Result<HashSet<&'a Subscription>, String>
Filters a list of incoming subscriptions and returns a filtered set
By default this deduplicates the subscriptions and calls
Self::filter_incoming_subscription_set
on the filtered set.source§fn filter_incoming_subscription_set<'a>(
&mut self,
subscriptions: HashSet<&'a Subscription>,
_currently_subscribed_topics: &BTreeSet<TopicHash>,
) -> Result<HashSet<&'a Subscription>, String>
fn filter_incoming_subscription_set<'a>( &mut self, subscriptions: HashSet<&'a Subscription>, _currently_subscribed_topics: &BTreeSet<TopicHash>, ) -> Result<HashSet<&'a Subscription>, String>
Filters a set of deduplicated subscriptions
By default this filters the elements based on
Self::allow_incoming_subscription
.source§fn allow_incoming_subscription(&mut self, subscription: &Subscription) -> bool
fn allow_incoming_subscription(&mut self, subscription: &Subscription) -> bool
Returns true iff we allow an incoming subscription.
This is used by the default implementation of filter_incoming_subscription_set to decide
whether to filter out a subscription or not.
By default this uses can_subscribe to decide the same for incoming subscriptions as for
outgoing ones.
