Account reader

Required Methods

fn changed_accounts_with_range( &self, _range: RangeInclusive<u64>, ) -> Result<BTreeSet<Address>, ProviderError>

Iterate over account changesets and return all account address that were changed.

fn basic_accounts( &self, _iter: impl IntoIterator<Item = Address>, ) -> Result<Vec<(Address, Option<Account>)>, ProviderError>

Get basic account information for multiple accounts. A more efficient version than calling AccountReader::basic_account repeatedly.

Returns None if the account doesn’t exist.

fn changed_accounts_and_blocks_with_range( &self, range: RangeInclusive<u64>, ) -> Result<BTreeMap<Address, Vec<u64>>, ProviderError>

Iterate over account changesets and return all account addresses that were changed alongside each specific set of blocks.

NOTE: Get inclusive range of blocks.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
