[][src]Struct substrate_subxt::EventSubscription

pub struct EventSubscription<T: Runtime> { /* fields omitted */ }

Event subscription simplifies filtering a storage change set stream for events of interest.

Implementations

impl<T: Runtime> EventSubscription<T>[src]

pub fn new(
    subscription: Subscription<StorageChangeSet<T::Hash>>,
    decoder: EventsDecoder<T>
) -> Self
[src]

Creates a new event subscription.

pub fn filter_block(&mut self, block: T::Hash)[src]

Only returns events contained in the block with the given hash.

pub fn filter_extrinsic(&mut self, block: T::Hash, ext_index: usize)[src]

Only returns events from block emitted by extrinsic with index.

pub fn filter_event<E: Event<T>>(&mut self)[src]

Filters events by type.

pub async fn next<'_>(&'_ mut self) -> Option<Result<RawEvent, Error>>[src]

Gets the next event.
