Ecto.Adapters.Connection behaviour
Behaviour for connection processes.
In order to use a connection, adapter developers need to implement
two callbacks in a module, connect/1 and disconnect/1 defined
in this module. The connection is started by passing the module that
implements the callbacks and as well as the connection arguments.
Callbacks
Specs:
- connect(Keyword.t) :: {:ok, pid} | {:error, term}
Connects to the underlying database.
Should return a process which is linked to the caller process or an error.
Specs:
- disconnect(pid) :: :ok
Disconnects the given pid.
If the given pid no longer exists, it should not raise.
