Campo	Tipo	Descripción	Fuente
`Skipper`	`Skipper`	Skipper defines a function to skip middleware.	L21
`Handler`	`BodyDumpHandler`	Handler receives request, response payloads and handler error if there are any. Required.	L25
`MaxRequestBytes`	`int64`	MaxRequestBytes limits how much of the request body to dump. If the request body exceeds this limit, only the first MaxRequestBytes are dumped. The handler callback receives truncated data. Default: 5 * MB (5,242,880 bytes) Set to -1 to disable limits (not recommended in production).	L32
`MaxResponseBytes`	`int64`	MaxResponseBytes limits how much of the response body to dump. If the response body exceeds this limit, only the first MaxResponseBytes are dumped. The handler callback receives truncated data. Default: 5 * MB (5,242,880 bytes) Set to -1 to disable limits (not recommended in production).	L39
