impl<'a> Prefixer<'a> for Hash

fn prefix(&self) -> Vec<Key<'_>>

returns 0 or more namespaces that should be length-prefixed and concatenated for range searches

fn joined_prefix(&self) -> Vec<u8>

impl<'a> PrimaryKey<'a> for Hash

type Prefix = ()

These associated types need to implement Prefixer, so that they can be useful arguments for prefix(), sub_prefix(), and their key-deserializable variants.
