function ~Codec

~Codec() override =default

function encodeNode

virtual outcome::result< base::Buffer > encodeNode(
    const Node & node
) const =0

Encode node to byte representation.

Parameters:

• node node in the trie

Return: encoded representation of the node

Reimplemented by: sgns::storage::trie::SuperGeniusCodec::encodeNode

function decodeNode

virtual outcome::result< std::shared_ptr< Node > > decodeNode(
    const base::Buffer & encoded_data
) const =0

Decode node from bytes.

Parameters:

• encoded_data a buffer containing encoded representation of a node

Return: a node in the trie

Reimplemented by: sgns::storage::trie::SuperGeniusCodec::decodeNode

function merkleValue

virtual base::Buffer merkleValue(
    const base::Buffer & buf
) const =0

Get the merkle value of a node.

Parameters:

• buf byte representation of the node

Return: hash of the buffer, or the buffer itself if it is shorter than the hash

Reimplemented by: sgns::storage::trie::SuperGeniusCodec::merkleValue

function hash256

virtual base::Hash256 hash256(
    const base::Buffer & buf
) const =0

Get the hash of a node.

Parameters:

• buf byte representation of the node

Return: hash of the buffer

Reimplemented by: sgns::storage::trie::SuperGeniusCodec::hash256
