Chain operations that read on-chain node accounts.

Required Methods

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

where 'a: 'async_trait, Self: '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 'life0: 'async_trait, Self: '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.
