defmodule Phoenix.Endpoint.RenderErrors do
# This module is used to catch failures and render them using a view.
#
# This module is automatically used in `Phoenix.Endpoint` where it
# overrides `call/2` to provide rendering. Once the error is
# rendered, the error is reraised unless it is a NoRouteError.
#
# ## Options
#
# * `:view` - the name of the view we render templates against
# * `:format` - the format to use when none is available from the request
