impl StateBuilder<EmptyDB>

pub fn new() -> Self

Create a new builder with an empty database.

If you want to instantiate it with a specific database, use new_with_database.

impl<DB: Database> StateBuilder<DB>

pub fn new_with_database(database: DB) -> Self

Create a new builder with the given database.

pub fn with_database<ODB: Database>(self, database: ODB) -> StateBuilder<ODB>

Set the database.

pub fn with_database_ref<ODB: DatabaseRef>( self, database: ODB ) -> StateBuilder<WrapDatabaseRef<ODB>>

Takes DatabaseRef and wraps it with WrapDatabaseRef.

pub fn with_database_boxed<Error>( self, database: DBBox<'_, Error> ) -> StateBuilder<DBBox<'_, Error>>

With boxed version of database.

pub fn without_state_clear(self) -> Self

By default state clear flag is enabled but for initial sync on mainnet we want to disable it so proper consensus changes are in place.

pub fn with_bundle_prestate(self, bundle: BundleState) -> Self

Allows setting prestate that is going to be used for execution. This bundle state will act as additional layer of cache. and State after not finding data inside StateCache will try to find it inside BundleState.

On update Bundle state will be changed and updated.

pub fn with_bundle_update(self) -> Self

Make transitions and update bundle state.

This is needed option if we want to create reverts and getting output of changed states.

pub fn with_cached_prestate(self, cache: CacheState) -> Self

It will use different cache for the state. If set, it will ignore bundle prestate. and will ignore without_state_clear flag as cache contains its own state_clear flag.

This is useful for testing.

pub fn with_background_transition_merge(self) -> Self

Starts the thread that will take transitions and do merge to the bundle state in the background.

pub fn with_block_hashes(self, block_hashes: BTreeMap<u64, B256>) -> Self

pub fn build(self) -> State<DB>
