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>)`
