A trait specifically for writing state changes or reverts

Required Associated Types

type Receipt: 'static

Receipt type included into [ExecutionOutcome].

Required Methods

fn write_state<'a>( &self, execution_outcome: impl Into<WriteStateInput<'a, Self::Receipt>>, is_value_known: OriginalValuesKnown, config: StateWriteConfig, ) -> ProviderResult<()>

Write the state and optionally receipts to the database.

Use config to skip writing certain data types when they are written elsewhere.

fn write_state_reverts( &self, reverts: PlainStateReverts, first_block: BlockNumber, config: StateWriteConfig, ) -> ProviderResult<()>

Write state reverts to the database.

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

Use config to skip writing certain data types when they are written elsewhere.

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

Write state changes to the database.

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

Writes the hashed state changes to the database

fn remove_state_above(&self, block: BlockNumber) -> ProviderResult<()>

Remove the block range of state above the given block. The state of the passed block is not removed.

fn take_state_above( &self, block: BlockNumber, ) -> ProviderResult<ExecutionOutcome<Self::Receipt>>

Take the block range of state, recreating the [ExecutionOutcome]. The state of the passed block is not removed.

Dyn Compatibility

This trait is not dyn compatible.

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