Struct sp_storage::ChildTrieParentKeyId

[+] Show declaration

pub struct ChildTrieParentKeyId { /* fields omitted */ }

[−] Expand description

A child trie of default type. It uses the same default implementation as the top trie, top trie being a child trie with no keyspace and no storage key. Its keyspace is the variable (unprefixed) part of its storage key. It shares its trie nodes backend storage with every other child trie, so its storage key needs to be a unique id that will be use only once. Those unique id also required to be long enough to avoid any unique id to be prefixed by an other unique id.
