Expand description

Trie Errors.

These borrow the data within them to avoid excessive copying on every trie operation.

Variants§

§

InvalidStateRoot(T)

Attempted to create a trie with a state root not in the DB.

§

IncompleteDatabase(T)

Trie item not found in the database,

§

ValueAtIncompleteKey(Vec<u8>, u8)

A value was found in the trie with a nibble key that was not byte-aligned. The first parameter is the byte-aligned part of the prefix and the second parameter is the remaining nibble.

§

DecoderError(T, E)

Corrupt Trie item.

§

InvalidHash(T, Vec<u8>)

Hash is not value.
