An HTTP status code (status-code in RFC 7230 et al.).

This enum contains all common status codes and an Unregistered extension variant. It allows status codes in the range [0, 65535], as any u16 integer may be used as a status code for XHR requests. It is recommended to only use values between [100, 599], since only these are defined as valid status codes with a status class by HTTP.

IANA maintain the Hypertext Transfer Protocol (HTTP) Status Code Registry which is the source for this enum (with one exception, 418 I'm a teapot, which is inexplicably not in the register).

Unregistered(u16)

A status code not in the IANA HTTP status code registry or very well known

Methods

impl StatusCode

pub fn try_from(n: u16) -> Result<StatusCode, InvalidStatusCode>

Try to convert a u16 into a StatusCode.

Errors

This will return an error if the provided argument is not within the range 100...599.

Note

This function is temporary. When the TryFrom trait becomes stable, this will be deprecated and replaced by TryFrom<u16>.

pub fn as_u16(&self) -> u16

Get the u16 code from this StatusCode.

Also available as From/Into<u16>.

Example

use hyper::StatusCode;

let status = StatusCode::Ok;
assert_eq!(status.as_u16(), 200);

// Into
let num: u16 = status.into();
assert_eq!(num, 200);

// From
let other = u16::from(status);
assert_eq!(num, other);

pub fn canonical_reason(&self) -> Option<&'static str>

Get the standardised reason-phrase for this status code.

This is mostly here for servers writing responses, but could potentially have application at other times.

The reason phrase is defined as being exclusively for human readers. You should avoid deriving any meaning from it at all costs.

Bear in mind also that in HTTP/2.0 the reason phrase is abolished from transmission, and so this canonical reason phrase really is the only reason phrase you’ll find.

pub fn is_informational(&self) -> bool

Check if this StatusCode is within 100-199.

pub fn is_success(&self) -> bool

Check if this StatusCode is within 200-299.

pub fn is_redirection(&self) -> bool

Check if this StatusCode is within 300-399.

pub fn is_client_error(&self) -> bool

Check if this StatusCode is within 400-499.

pub fn is_server_error(&self) -> bool

Check if this StatusCode is within 500-599.

pub fn is_strange_status(&self) -> bool

Check if this StatusCode is not within 100-599.
