Member Function Documentation

virtual RootHash kagome::storage::trie::TrieSerializer::getEmptyRootHash ( ) const

pure virtual

Returns

root hash of an empty trie

Implemented in kagome::storage::trie::TrieSerializerImpl.

virtual outcome::result<std::shared_ptr<PolkadotTrie> > kagome::storage::trie::TrieSerializer::retrieveTrie ( const common::Buffer &  db_key ) const

pure virtual

Fetches a trie from the storage. A nullptr is returned in case that there is no entry for provided key.

Implemented in kagome::storage::trie::TrieSerializerImpl.

virtual outcome::result<RootHash> kagome::storage::trie::TrieSerializer::storeTrie ( PolkadotTrie &  trie )

pure virtual

Writes a trie to a storage, recursively storing its nodes.

Implemented in kagome::storage::trie::TrieSerializerImpl.
