Struct trie_db::TrieBuilder

source · [−]

pub struct TrieBuilder<'a, T: TrieLayout, DB> {
    pub root: Option<TrieHash<T>>,
    /* private fields */
}

Expand description

Get trie root and insert visited node in a hash_db. As for all ProcessEncodedNode implementation, it is only for full trie parsing (not existing trie).

Fields

root: Option<TrieHash<T>>
