pub struct StorageProof { /* private fields */ }
Expand description

A proof that some set of key-value pairs are included in the storage trie. The proof contains the storage values so that the partial storage backend can be reconstructed by a verifier that does not already have access to the key-value pairs.

The proof consists of the set of serialized nodes in the storage trie accessed when looking up the keys covered by the proof. Verifying the proof requires constructing the partial trie from the serialized nodes and performing the key lookups.

Implementations

Constructs a storage proof from a subset of encoded trie nodes in a storage backend.

Returns a new empty proof.

An empty proof is capable of only proving trivial statements (ie. that an empty set of key-value pairs exist in storage).

Returns whether this is an empty proof.

Convert into an iterator over encoded trie nodes in lexicographical order constructed from the proof.

Create an iterator over encoded trie nodes in lexicographical order constructed from the proof.

Convert into plain node vector.

Creates a MemoryDB from Self.

Creates a MemoryDB from Self reference.

Merges multiple storage proofs covering potentially different sets of keys into one proof covering all keys. The merged proof output may be smaller than the aggregate size of the input proofs due to deduplication of trie nodes.

Encode as a compact proof with default trie layout.

Encode as a compact proof with default trie layout.

Returns the estimated encoded size of the compact proof.

Running this operation is a slow operation (build the whole compact proof) and should only be in non sensitive path.

Return None on error.
