Storage reader

Required Methods

fn plain_state_storages( &self, addresses_with_keys: impl IntoIterator<Item = (Address, impl IntoIterator<Item = FixedBytes<32>>)>, ) -> Result<Vec<(Address, Vec<StorageEntry>)>, ProviderError>

Get plainstate storages for addresses and storage keys.

fn changed_storages_with_range( &self, range: RangeInclusive<u64>, ) -> Result<BTreeMap<Address, BTreeSet<FixedBytes<32>>>, ProviderError>

Iterate over storage changesets and return all storage slots that were changed.

fn changed_storages_and_blocks_with_range( &self, range: RangeInclusive<u64>, ) -> Result<BTreeMap<(Address, FixedBytes<32>), Vec<u64>>, ProviderError>

Iterate over storage changesets and return all storage slots 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".
