defmodule Credo.Check.Consistency.MultiAliasImportRequireUse do
@moduledoc """
When using alias, import, require or use for multiple names from the same
namespace, you have two options:
Use single instructions per name:
alias Ecto.Query
alias Ecto.Schema
alias Ecto.Multi
or use one multi instruction per namespace:
alias Ecto.{Query, Schema, Multi}
While this is not necessarily a concern for the correctness of your code,
you should use a consistent style throughout your codebase.
