Implementations

source

impl<'a, P, R> SubscriptionStream<'a, P, R>where
P: PubsubClient,
R: DeserializeOwned,

source

pub fn new(id: U256, provider: &'a Provider) -> Result<Self, P::Error>

Creates a new subscription stream for the provided subscription id.

Note

Most providers treat SubscriptionStream IDs as global singletons. Instantiating this directly with a known ID will likely cause any existing streams with that ID to end. To avoid this, start a new stream using Provider::subscribe instead of SubscriptionStream::new.

source

pub async fn unsubscribe(&self) -> Result<bool, ProviderError>

Unsubscribes from the subscription.

source

pub fn set_loaded_elements(&mut self, loaded_elements: VecDeque<R>)

source

impl<'a, P> SubscriptionStream<'a, P, TxHash>where
P: PubsubClient,

source

pub fn transactions_unordered(self, n: usize) -> TransactionStream<'a, P, Self>

Returns a stream that yields the Transactions for the transaction hashes this stream yields.

This internally calls Provider::get_transaction with every new transaction. No more than n futures will be buffered at any point in time, and less than n may also be buffered depending on the state of each future.
