Expand description

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.

If you encounter a status code that you do not know how to deal with, you should treat it as the x00 status code—e.g. for code 123, treat it as 100 (Continue). This can be achieved with self.class().default_code():

let status = StatusCode::Unregistered(123);
assert_eq!(status.class().default_code(), StatusCode::Continue);

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).

Implementations§

source§

impl StatusCode

source

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.

source

pub fn class(&self) -> StatusClass

Determine the class of a status code, based on its first digit.

source

pub fn is_informational(&self) -> bool

Check if class is Informational.

source

pub fn is_success(&self) -> bool

Check if class is Success.

source

pub fn is_redirection(&self) -> bool

Check if class is Redirection.

source

pub fn is_client_error(&self) -> bool

Check if class is ClientError.

source

pub fn is_server_error(&self) -> bool

Check if class is ServerError.

source

pub fn is_strange_status(&self) -> bool

Check if class is NoClass
