Struct LeafNode

pub struct LeafNode {
    pub key: Nibbles,
    pub value: Vec<u8>,
}

Expand description

Re-export A leaf node represents the endpoint or terminal node in the trie. In other words, a leaf node is where actual values are stored.

A leaf node consists of two parts: the key (or path) and the value. The key is typically the remaining portion of the key after following the path through the trie, and the value is the data associated with the full key. When searching the trie for a specific key, reaching a leaf node means that the search has successfully found the value associated with that key.

Fields§

§key: Nibbles

The key for this leaf node.

§value: Vec<u8>

The node value.

Implementations§

impl LeafNode

pub const EVEN_FLAG: u8 = 0x20

The flag representing the even number of nibbles in the leaf key.

pub const ODD_FLAG: u8 = 0x30

The flag representing the odd number of nibbles in the leaf key.

pub const fn new(key: Nibbles, value: Vec<u8>) -> LeafNode

Creates a new leaf node with the given key and value.

pub fn as_ref(&self) -> LeafNodeRef<'_>
