Type Alias StorageProofCalculator 

pub type StorageProofCalculator<TC, HC> = ProofCalculator<TC, HC, StorageValueEncoder>;

A proof calculator for storage tries.

Aliased Type

pub struct StorageProofCalculator<TC, HC> { /* private fields */ }

Implementations

impl<TC, HC> StorageProofCalculator<TC, HC>

where TC: TrieStorageCursor, HC: HashedStorageCursor<Value = U256>,

pub fn new_storage(trie_cursor: TC, hashed_cursor: HC) -> Self

Create a new StorageProofCalculator instance.

pub fn storage_proof( &mut self, hashed_address: B256, targets: &mut [ProofV2Target], ) -> Result<Vec<ProofTrieNodeV2>, StateProofError>

Generate a proof for a storage trie at the given hashed address.

Given a set of ProofV2Targets, returns nodes whose paths are a prefix of any target. The returned nodes are sorted in depth-first post-order (children before parents).

Targets may be supplied in any order. Calculation sorts the slice in place by known parent context, then by key within each group.

pub fn storage_root_node( &mut self, hashed_address: B256, ) -> Result<ProofTrieNodeV2, StateProofError>

Calculates the root node of a storage trie.

This method does not accept targets nor retain proofs. Returns the root node which can be used to compute the root hash via Self::compute_root_hash.

pub fn storage_root( &mut self, hashed_address: B256, ) -> Result<B256, StateProofError>

Calculates the storage root hash of the account at hashed_address.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
