Trait Implementations

source

impl<T, S> TopicSubscriptionFilter for CombinedSubscriptionFilters<T, S> where
T: TopicSubscriptionFilter,
S: TopicSubscriptionFilter,

source

pub fn can_subscribe(&mut self, topic_hash: &TopicHash) -> bool

Returns true iff the topic is of interest and we can subscribe to it.

source

pub fn filter_incoming_subscription_set(
 &mut self,
 subscriptions: HashSet<&'a GossipsubSubscription, RandomState>,
 currently_subscribed_topics: &BTreeSet<TopicHash>
) -> Result<HashSet<&'a GossipsubSubscription, RandomState>, String>

Filters a set of deduplicated subscriptions By default this filters the elements based on Self::allow_incoming_subscription. Read more

source

fn filter_incoming_subscriptions(
 &mut self,
 subscriptions: &'a [GossipsubSubscription],
 currently_subscribed_topics: &BTreeSet<TopicHash>
) -> Result<HashSet<&'a GossipsubSubscription, RandomState>, 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. Read more

source

fn allow_incoming_subscription(
&mut self,
subscription: &GossipsubSubscription
) -> 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. Read more
