Implementations§

Source§

impl<T, H> StateRoot<T, H>

Source

pub fn new(trie_cursor_factory: T, hashed_cursor_factory: H) -> Self

Creates StateRoot with trie_cursor_factory and hashed_cursor_factory. All other parameters are set to reasonable defaults.

The cursors created by given factories are then used to walk through the accounts and calculate the state root value with.

Source

pub fn with_prefix_sets(self, prefix_sets: TriePrefixSets) -> Self

Set the prefix sets.

Source

pub const fn with_threshold(self, threshold: u64) -> Self

Set the threshold.

Source

pub const fn with_no_threshold(self) -> Self

Set the threshold to maximum value so that intermediate progress is not returned.

Source

pub fn with_intermediate_state( self, state: Option<IntermediateStateRootState>, ) -> Self

Set the previously recorded intermediate state.

Source

pub fn with_hashed_cursor_factory<HF>( self, hashed_cursor_factory: HF, ) -> StateRoot<T, HF>

Source

pub fn with_trie_cursor_factory<TF>( self, trie_cursor_factory: TF, ) -> StateRoot<TF, H>

Source§

impl<T, H> StateRoot<T, H>
where T: TrieCursorFactory + Clone, H: HashedCursorFactory + Clone,

Source

pub fn root_with_updates(self) -> Result<(B256, TrieUpdates), StateRootError>

Walks the intermediate nodes of existing state trie (if any) and hashed entries. Feeds the nodes into the hash builder. Collects the updates in the process.

Ignores the threshold.

§Returns

The intermediate progress of state root computation and the trie updates.

Source

pub fn root(self) -> Result<B256, StateRootError>

Walks the intermediate nodes of existing state trie (if any) and hashed entries. Feeds the nodes into the hash builder.

§Returns

The state root hash.

Source

pub fn root_with_progress(self) -> Result<StateRootProgress, StateRootError>

Walks the intermediate nodes of existing state trie (if any) and hashed entries. Feeds the nodes into the hash builder. Collects the updates in the process.

§Returns

The intermediate progress of state root computation.
