Overview

This is a role for KiokuDB::Role::Immutable objects whose IDs depend on their content, or in other words content addressable objects.

A canonical example is a string identified by its SHA-1 hash, as is demonstrated in the "SYNOPSIS".

Objects which do this role are never updated in the database just like KiokuDB::Role::Immutable objects.

Additionally, it is not an error to insert such objects twice since the objects are assumed to be identical.
