Account reader

Required Methods

fn changed_accounts_with_range( &self, _range: impl RangeBounds<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", so this trait is not object safe.
