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.
