[−][src]Struct substrate_subxt::EventSubscription
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]
subscription: Subscription<StorageChangeSet<T::Hash>>,
decoder: EventsDecoder<T>
) -> Self
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.
