Servant.Server.Internal.ErrorFormatter

A collection of error formatters for different situations.

If you need to override one of them, use defaultErrorFormatters with record update syntax.

A custom formatter for errors produced by parsing combinators like ReqBody or Capture.

A TypeRep argument described the concrete combinator that raised the error, allowing formatter to customize the message for different combinators.

A full Request is also passed so that the formatter can react to Accept header, for example.

This formatter does not get neither TypeRep nor error message.

Context that contains default error formatters.

Default formatters will just return HTTP 400 status code with error message as response body.
