Constructors

ErrorFormatters
Fields bodyParserErrorFormatter :: ErrorFormatter Format error from parsing the request body. urlParseErrorFormatter :: ErrorFormatter Format error from parsing url parts or query parameters. headerParseErrorFormatter :: ErrorFormatter Format error from parsing request headers. notFoundErrorFormatter :: NotFoundErrorFormatter Format error for not found URLs.

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.
