Enum diem_jellyfish_merkle::node_type::Node

pub enum Node<V> {
    Null,
    Internal(InternalNode),
    Leaf(LeafNode<V>),
}

The concrete node type of JellyfishMerkleTree.

Variants

Null

Represents null.

Internal(InternalNode)

A wrapper of InternalNode.

Leaf(LeafNode<V>)

A wrapper of LeafNode.

Implementations

impl<V> Node<V>where V: Value,

pub fn new_null() -> Self

Creates the Null variant.

pub fn new_internal(children: HashMap<Nibble, Child>) -> Self

Creates the Internal variant.

pub fn new_leaf(account_key: HashValue, value: V) -> Self

Creates the Leaf variant.

pub fn is_leaf(&self) -> bool

Returns true if the node is a leaf node.

pub fn encode(&self) -> Result<Vec<u8>>

Serializes to bytes for physical storage.

pub fn hash(&self) -> HashValue

Computes the hash of nodes.

pub fn decode(val: &[u8]) -> Result<Node<V>>

Recovers from serialized bytes in physical storage.

Trait Implementations

impl<V: Clone> Clone for Node<V>

fn clone(&self) -> Node<V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<V: Debug> Debug for Node<V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<V> From<InternalNode> for Node<V>

fn from(node: InternalNode) -> Self

Converts to this type from the input type.

impl<V> From<LeafNode<V>> for Node<V>

fn from(node: LeafNode<V>) -> Self

Converts to this type from the input type.

impl<V: PartialEq> PartialEq<Node<V>> for Node<V>

fn eq(&self, other: &Node<V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
