Response Status Codes
The status-code element is a three-digit integer code giving the result of the attempt to understand and satisfy the request.
See RFC7231§6 for more details.
For the most part, this module is a proxy to Httpaf.Status. Its informational type, however, removes support for the Switching_protocols tag, as per the HTTP/2 spec (relevant portion reproduced below).
From RFC7540§8.1.1: HTTP/2 removes support for the 101 (Switching Protocols) informational status code (RFC7231, Section 6.2.2).
See RFC7540§8.1.1 for more details.
The 1xx (Informational) class of status code indicates an interim response for communicating connection status or request progress prior to completing the requested action and sending a final response.
See RFC7231§6.2 for more details.
type successful = Httpaf.Status.successfulThe 2xx (Successful) class of status code indicates that the client's request was successfully received, understood, and accepted.
See RFC7231§6.3 for more details.
type redirection = Httpaf.Status.redirectionThe 3xx (Redirection) class of status code indicates that further action needs to be taken by the user agent in order to fulfill the request.
See RFC7231§6.4 for more details.
type client_error = Httpaf.Status.client_errorThe 4xx (Client Error) class of status code indicates that the client seems to have erred.
See RFC7231§6.5 for more details.
type server_error = Httpaf.Status.server_errorThe 5xx (Server Error) class of status code indicates that the server is aware that it has erred or is incapable of performing the requested method.
See RFC7231§6.6 for more details.
type standard = [ | informational| Httpaf.Status.successful| Httpaf.Status.redirection| Httpaf.Status.client_error| Httpaf.Status.server_error
]The status codes defined in the HTTP/1.1 RFCs, excluding the Switching
Protocols status as per the HTTP/2 RFC.
The standard codes along with support for custom codes.
val default_reason_phrase : standard -> stringdefault_reason_phrase standard is the example reason phrase provided by RFC7231 for the standard status code. The RFC allows servers to use reason phrases besides these in responses.
val to_code : t -> intto_code t is the integer representation of t.
val of_code : int -> tof_code i is the t representation of i. of_code raises Failure if i is not a positive three-digit number.
val unsafe_of_code : int -> tunsafe_of_code i is equivalent to of_code i, except it accepts any positive code, regardless of the number of digits it has. On negative codes, it will still raise Failure.
val is_informational : t -> boolis_informational t is true iff t belongs to the Informational class of status codes.
val is_successful : t -> boolis_successful t is true iff t belongs to the Successful class of status codes.
val is_redirection : t -> boolis_redirection t is true iff t belongs to the Redirection class of status codes.
val is_client_error : t -> boolis_client_error t is true iff t belongs to the Client Error class of status codes.
val is_server_error : t -> boolis_server_error t is true iff t belongs to the Server Error class of status codes.
val is_error : t -> boolis_server_error t is true iff t belongs to the Client Error or Server Error class of status codes.
