impl<'a, L: Serialize + DeserializeOwned + Clone + Debug + PartialEq, H: Hasher<L>> MerkleTree<L, H> for SparseMerkleTree<'a, L, H>

source

fn init(
 &self,
 storage: &mut dyn Storage,
 level: u8,
 default_leaf: L,
 hasher: &H
) -> Result<(), MerkleTreeError>

Initize the tree.

source

fn is_valid_root(
 &self,
 storage: &dyn Storage,
 root: &L
) -> Result<bool, MerkleTreeError>

Check if the root is valid for the tree.

source

fn insert(
 &self,
 storage: &mut dyn Storage,
 leaf: L,
 hasher: &H
) -> Result<(u64, L), MerkleTreeError>

Insert the leaf into the next index slot of the tree. Return the leaf’s index and the updated root. Read more
