pub struct EventApi { /* private fields */ }
Expand description
Defines methods to fetch, query, or subscribe to events on the Iota network.
Implementations§
source§impl EventApi
impl EventApi
sourcepub async fn subscribe_event(
&self,
filter: EventFilter,
) -> IotaRpcResult<impl Stream<Item = IotaRpcResult<IotaEvent>>>
pub async fn subscribe_event( &self, filter: EventFilter, ) -> IotaRpcResult<impl Stream<Item = IotaRpcResult<IotaEvent>>>
Subscribe to receive a stream of filtered events.
Subscription is only possible via WebSockets. For a list of possible event filters, see EventFilter.
§Examples
use std::str::FromStr;
use futures::StreamExt;
use iota_json_rpc_types::EventFilter;
use iota_sdk::IotaClientBuilder;
use iota_types::base_types::IotaAddress;
#[tokio::main]
async fn main() -> Result<(), anyhow::Error> {
let iota = IotaClientBuilder::default()
.ws_url("wss://api.mainnet.iota.cafe")
.build("https://api.mainnet.iota.cafe")
.await?;
let mut subscribe_all = iota
.event_api()
.subscribe_event(EventFilter::All(vec![]))
.await?;
loop {
println!("{:?}", subscribe_all.next().await);
}
Ok(())
}
sourcepub async fn get_events(
&self,
digest: TransactionDigest,
) -> IotaRpcResult<Vec<IotaEvent>>
pub async fn get_events( &self, digest: TransactionDigest, ) -> IotaRpcResult<Vec<IotaEvent>>
Get a list of events for the given transaction digest.
sourcepub async fn query_events(
&self,
query: EventFilter,
cursor: impl Into<Option<EventID>>,
limit: impl Into<Option<usize>>,
descending_order: bool,
) -> IotaRpcResult<EventPage>
pub async fn query_events( &self, query: EventFilter, cursor: impl Into<Option<EventID>>, limit: impl Into<Option<usize>>, descending_order: bool, ) -> IotaRpcResult<EventPage>
Get a list of filtered events. The response is paginated and can be ordered ascending or descending.
For a list of possible event filters, see EventFilter.
sourcepub fn get_events_stream(
&self,
query: EventFilter,
cursor: impl Into<Option<EventID>>,
descending_order: bool,
) -> impl Stream<Item = IotaEvent> + '_
pub fn get_events_stream( &self, query: EventFilter, cursor: impl Into<Option<EventID>>, descending_order: bool, ) -> impl Stream<Item = IotaEvent> + '_
Get a stream of filtered events which can be ordered ascending or descending.
For a list of possible event filters, see EventFilter.
