defmodule Absinthe.Phase.Document.Arguments.CoerceEnums do
@moduledoc false
# Coerce variable string inputs to enums when appropriate.
#
# A literal enum like `foo(arg: ENUM)` is parsed as an `Input.Enum` struct.
#
# However when a variable is used `foo(arg: $enumVar)` the variable input ends up
# being an `Input.String` because the variable handler does not yet know the
# schema type. This phase coerces string to enum inputs when the schema type
# is an Enum.
