Source 
pub struct MerkleTrie(/* private fields */);
Expand description

A sparse Merkle Patricia trie storing byte values.

Implementations§

Source§

impl MerkleTrie

Source

pub fn get(&self, key: impl AsRef<[u8]>) -> Option<&[u8]>

Returns a reference to the byte value corresponding to the key.

It panics when neither inclusion nor exclusion of the key can be guaranteed.

Source

pub fn get_rlp<T: Decodable>(&self, key: impl AsRef<[u8]>) -> Result<Option<T>>

Returns the RLP decoded value corresponding to the key.

It panics when neither inclusion nor exclusion of the key can be guaranteed or when the value is not RLP decodable.

Source

pub fn size(&self) -> usize

Returns the number of full nodes in the trie.

A full node is a node that needs to be fully encoded to compute the root hash.

Source

pub fn hash_slow(&self) -> B256

Returns the hash of the trie’s root node.

Source

pub fn hydrate_from_rlp_nodes<T: AsRef<[u8]>>( &mut self, nodes: impl IntoIterator<Item = T>, ) -> Result<()>

Resolves currently unresolved nodes within the trie using the provided RLP-encoded nodes.

This method iterates through the provided RLP-encoded nodes, computes the Keccak-256 hash of each node, and attempts to replace any internal Node::Digest entries matching that hash with the decoded node.

Source

pub fn from_rlp_nodes<T: AsRef<[u8]>>( nodes: impl IntoIterator<Item = T>, ) -> Result<Self>

Creates a new trie from the given RLP encoded nodes.

The first node provided must always be the root node. The remaining nodes can be in any order and are resolved if they are referenced (directly or indirectly) by the root node. Referenced children that cannot be resolved are represented by their hash. This guarantees that the root hash can be computed and matches the root hash of the fully resolved trie.

Source

pub fn from_digest(digest: B256) -> Self

Creates a new trie corresponding to the given digest.
