Enum trie_db::triedbmut::Value

source ·
pub enum Value<L: TrieLayout> {
    Inline(Bytes),
    Node(TrieHash<L>),
    NewNode(Option<TrieHash<L>>, Bytes),
}
Expand description

Value representation for Node.

Variants§

§

Inline(Bytes)

Value bytes inlined in a trie node.

§

Node(TrieHash<L>)

Hash of the value.

§

NewNode(Option<TrieHash<L>>, Bytes)

Hash of value bytes if calculated and value bytes. The hash may be undefined until it node is added to the db.
