Required Methods

fn write_state_reverts( &self, reverts: PlainStateReverts, first_block: u64, ) -> Result<(), ProviderError>

Write state reverts to the database.

NOTE: Reverts will delete all wiped storage from plain state.

fn write_state_changes( &self, changes: StateChangeset, ) -> Result<(), ProviderError>

Write state changes to the database.

fn write_hashed_state( &self, hashed_state: &HashedPostStateSorted, ) -> Result<(), ProviderError>

Writes the hashed state changes to the database

fn remove_state(&self, range: RangeInclusive<u64>) -> Result<(), ProviderError>

Remove the block range of state.

fn take_state( &self, range: RangeInclusive<u64>, ) -> Result<ExecutionOutcome, ProviderError>

Take the block range of state, recreating the ExecutionOutcome.
