Function sp_storage::well_known_keys::is_child_trie_key_valid

pub fn is_child_trie_key_valid(storage_key: &[u8]) -> bool

Determine whether a child trie key is valid.

For now, the only valid child trie keys are those starting with :child_storage:default:.

child_trie_root and child_delta_trie_root can panic if invalid value is provided to them.
