type TrieBackendStorage = <TrieBackend<Arc<dyn Storage<HashFor<B>>>, HashFor<B>> as StateBackend<HashFor<B>>>::TrieBackendStorage
Type of trie backend storage.
Get keyed storage or None if there is nothing associated.
Get keyed storage value hash or None if there is nothing associated.
Get keyed child storage or None if there is nothing associated.
true if a key exists in storage.
true if a key exists in child storage.
Return the next key in storage in lexicographic order or None
if there is no value.
Return the next key in child storage in lexicographic order or None
if there is no value.
Retrieve all entries keys which start with the given prefix and
call f
for each of those keys. Read more
Retrieve all entries keys and values of which start with the given prefix and

for each of those keys. Read more
Iterate over storage starting at key, for a given prefix and child trie.
Aborts as soon as f
returns false.
Warning, this fails at first error when usual iteration skips errors.
If allow_missing
is true, iteration stops when it reaches a missing trie node.
Otherwise an error is produced. Read more
