Merkle Tree
Implementations§
source§impl MerkleTree
impl MerkleTree
sourcepub fn new(nodes: impl Into<Vec<MerkleNode>>) -> Self
pub fn new(nodes: impl Into<Vec<MerkleNode>>) -> Self
Creates a new MerkleTree from leaf nodes
sourcepub fn root_hash(&self) -> Digest32
pub fn root_hash(&self) -> Digest32
Returns the root hash for MerkleTree. If the tree is empty, then returns [0; 32]
sourcepub fn root_hash_special(&self) -> Digest32
pub fn root_hash_special(&self) -> Digest32
Returns the root hash for MerkleTree. If the tree is empty, then returns a special hash ‘0e5751c026e543b2e8ab2eb06099daa1d1e5df47778f7787faab45cdf12fe3a8’, which is extension/transaction root hash for genesis block See: https://github.com/ergoplatform/ergo/issues/1077
sourcepub fn get_elements_hash_index(&self) -> &HashMap<Digest32, usize>
pub fn get_elements_hash_index(&self) -> &HashMap<Digest32, usize>
Returns HashMap of hashes and their index in the tree
sourcepub fn proof_by_index(&self, leaf_index: usize) -> Option<MerkleProof>
pub fn proof_by_index(&self, leaf_index: usize) -> Option<MerkleProof>
Builds a crate::MerkleProof
for leaf_index. Returns None if index does not exist
sourcepub fn proof_by_element_hash(&self, hash: &Digest32) -> Option<MerkleProof>
pub fn proof_by_element_hash(&self, hash: &Digest32) -> Option<MerkleProof>
Builds a crate::MerkleProof
for given hash. Returns None if hash is not a leaf of tree
sourcepub fn proof_by_element(&self, data: &[u8]) -> Option<MerkleProof>
pub fn proof_by_element(&self, data: &[u8]) -> Option<MerkleProof>
Builds a crate::MerkleProof
for element, by searching for its hash in the tree
sourcepub fn proof_by_indices(
&self,
leaf_indices: &[usize]
) -> Option<BatchMerkleProof>
pub fn proof_by_indices( &self, leaf_indices: &[usize] ) -> Option<BatchMerkleProof>
Builds a crate::BatchMerkleProof
for given indices
