Common go ORM accepts struct as a value for modifying records which has a problem of unable to differentiate between an empty, nil, or undefined value. It’s a tricky problem especially when you want to have an endpoint that supports partial updates. Grimoire attempts to solve that problem by integrating Changeset system inspired from Elixir’s Ecto. Changeset is a form like entity which allows us to not only solve that problem but also help us with casting, validations, and constraints check.
