StateTrieOverlayManager

Struct StateTrieOverlayManager 

Source 
pub struct StateTrieOverlayManager<N: NodePrimitives = EthPrimitives> { /* private fields */ }
Expand description

Manages flattened state trie overlays for in-memory blocks.

The manager owns the in-memory block graph and a cache of flattened state trie overlays keyed by (anchor_hash, tip_hash).

Implementations§

Source§

impl<N: NodePrimitives> StateTrieOverlayManager<N>

Source

pub fn new(worker_pool: Arc<WorkerPool>) -> Self

Available on crate feature rayon only.

Create a new StateTrieOverlayManager backed by the given worker pool.

Source

pub fn insert_block(&self, block: ExecutedBlock<N>)

Inserts an executed in-memory block into the state trie overlay manager.

Source

pub fn remove_blocks(&self, hashes: impl IntoIterator<Item = B256>)

Removes blocks from the live block graph and prunes cached overlays that can no longer be built from the remaining blocks.

Source

pub fn overlay_for_parent( &self, parent_hash: B256, anchor_hash: B256, ) -> Result<(Arc<TrieUpdatesSorted>, Arc<HashedPostStateSorted>), StateTrieOverlayError>

Returns the flattened overlay from anchor_hash to parent_hash.

Source

pub fn anchor_for_parent( &self, parent_hash: B256, preferred_anchor: B256, ) -> Option<B256>

Returns preferred_anchor if it is on the parent chain, otherwise the first missing parent.

Returns None if parent_hash is not preferred_anchor and the manager does not contain a block for parent_hash, meaning there is no in-memory parent chain to inspect.
