Struct CompactLeaf

Source 
pub struct CompactLeaf<const HASH_SIZE: usize, H: Hasher<HASH_SIZE> + Clone> { /* private fields */ }
Expand description

A compact leaf is a leaf doesn’t require all the empty parts of the path to be inserted. When required we can extract all the branches on that path. The node hash is the hash of the node at the top of the path.

Implementations§

Source§

impl<const HASH_SIZE: usize, H: Hasher<HASH_SIZE> + Clone> CompactLeaf<HASH_SIZE, H>

Source

pub fn new( height: usize, key: [u8; HASH_SIZE], leaf: Leaf<HASH_SIZE, H>, empty_tree: Arc<Vec<Node<HASH_SIZE, H>>>, ) -> Self

Creates a new compact leaf.

Source

pub unsafe fn new_with_hash( node_hash: [u8; HASH_SIZE], leaf: Leaf<HASH_SIZE, H>, key: [u8; HASH_SIZE], ) -> Self

§Safety

The node hash won’t be recomputed so if the provided hash is incorrect the whole tree will be incorrect

Source

pub fn hash(&self) -> [u8; HASH_SIZE]

Returns the hash of the node at the top of the path.

Source

pub fn leaf(&self) -> &Leaf<HASH_SIZE, H>

Returns the leaf of the compact leaf.

Source

pub fn key(&self) -> &[u8; HASH_SIZE]

Returns the key of the compact leaf.

Source

pub fn sum(&self) -> u64

Returns the sum of the leaf.

Source

pub fn extract(&self, height: usize) -> Node<HASH_SIZE, H>

Extracts the branches on the path to the leaf.
