@spec all(map(), PowAssent.Config.t()) :: [map()] | no_return()

Lists all user identity associations for user.

This calls Pow.Ecto.UserIdentities.Context.all/2 or all/1 on a custom context module.

@spec create_user(map(), map(), map() | nil, PowAssent.Config.t()) ::
  {:ok, map()}
  | {:error, {:bound_to_different_user | :invalid_user_id_field, map()}}
  | {:error, map()}
  | no_return()

Creates user with user identity with the provided user params.

This calls Pow.Ecto.UserIdentities.Context.create_user/4 or create_user/3 on a custom context module.

@spec delete(map(), binary(), PowAssent.Config.t()) ::
  {:ok, {number(), nil}} | {:error, {:no_password, map()}} | no_return()

Deletes the user identity for user and strategy provider name.

This calls Pow.Ecto.UserIdentities.Context.delete/3 or delete/2 on a custom context module.

@spec get_user_by_provider_uid(binary(), binary(), PowAssent.Config.t()) ::
  map() | nil | no_return()

Retrieve a user with the strategy provider name and uid.

This calls Pow.Ecto.UserIdentities.Context.get_user_by_provider_uid/3 or get_user_by_provider_uid/2 on a custom context module.

@spec upsert(map(), map(), PowAssent.Config.t()) ::
  {:ok, map()}
  | {:error, {:bound_to_different_user, map()}}
  | {:error, map()}
  | no_return()

Upserts user identity for the user, and strategy provider name and uid.

This calls Pow.Ecto.UserIdentities.Context.upsert/3 or upsert/2 on a custom context module.

@spec user_identity_changeset(map(), map(), map(), PowAssent.Config.t()) ::
  map() | nil

Build a changeset from a blank user struct.

It'll use the schema module fetched from the config through Pow.Config.user!/1 and call user_identity_changeset/4 on it.
