Ecto.Adapters.Mnesia.Query behaviour (Ecto3 Mnesia v0.3.0) View Source

This module is responsible for building a query out of an Ecto Query.

Based on the complexity of the query, different translators can be used:

Ecto.Adapters.Mnesia.Query.Get for simple Repo.get -like queries
Ecto.Adapters.Mnesia.Query.Qlc for more complex ones
