Required Methods

fn stream_accounts<'a, 'async_trait>( &'a self, selector: AccountSelector, ) -> Pin<Box<dyn Future<Output = Result<BoxStream<'a, AccountEntry>, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait,

Returns on-chain node accounts with the given AccountSelector.

fn count_accounts<'life0, 'async_trait>( &'life0 self, selector: AccountSelector, ) -> Pin<Box<dyn Future<Output = Result<usize, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Counts the accounts with the given AccountSelector.

This is potentially done more effectively than counting more elements of the stream returned by ChainReadAccountOperations::stream_accounts.

fn await_key_binding<'life0, 'life1, 'async_trait>( &'life0 self, offchain_key: &'life1 OffchainPublicKey, timeout: Duration, ) -> Pin<Box<dyn Future<Output = Result<AccountEntry, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Waits for the account with the key-binding on the offchain_key to appear on-chain or the timeout expires.
