Enum SparseTrie

Source 
pub enum SparseTrie {
    Blind,
    Revealed(RevealedSparseTrie),
}
Expand description

Inner representation of the sparse trie. Sparse trie is blind by default until nodes are revealed.

Variants§

§

Blind

None of the trie nodes are known.

§

Revealed(RevealedSparseTrie)

The trie nodes have been revealed.
