Struct casper_execution_engine::storage::trie::merkle_proof::TrieMerkleProof [−][src]
A proof that a node with a specified key and value is present in the Merkle trie.
Given a state hash x, one can validate a proof p by checking x == p.compute_state_hash().
Implementations
impl<K, V> TrieMerkleProof<K, V>[src]
pub fn new(key: K, value: V, proof_steps: VecDeque<TrieMerkleProofStep>) -> Self[src]
Constructor for TrieMerkleProof
pub fn key(&self) -> &K[src]
Getter for the key in TrieMerkleProof
pub fn value(&self) -> &V[src]
Getter for the value in TrieMerkleProof
pub fn proof_steps(&self) -> &VecDeque<TrieMerkleProofStep>[src]
Getter for the proof steps in TrieMerkleProof
pub fn into_value(self) -> V[src]
Transforms a TrieMerkleProof into the value it contains
impl<K, V> TrieMerkleProof<K, V> where
K: ToBytes + Copy + Clone,
V: ToBytes + Clone, [src]
K: ToBytes + Copy + Clone,
V: ToBytes + Clone,
pub fn compute_state_hash(&self) -> Result<Blake2bHash, Error>[src]
Recomputes a state root hash from a TrieMerkleProof.
This is done in the following steps:
-
Using
TrieMerkleProof::keyandTrieMerkleProof::value, construct aTrie::Leafand compute a hash for that leaf. -
We then iterate over
TrieMerkleProof::proof_stepsleft to right, using the hash from the previous step combined with the next step to compute a new hash. -
When there are no more steps, we return the final hash we have computed.
The steps in this function reflect operations::rehash.
