Struct http::status::StatusCode[][src]

pub struct StatusCode(_);

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

Constants are provided for known status codes, including those in the IANA HTTP Status Code Registry.

Status code values in the range 100-999 (inclusive) are supported by this type. Values in the range 100-599 are semantically classified by the most significant digit. See StatusCode::is_success, etc. Values above 599 are unclassified but allowed for legacy compatibility, though their use is discouraged. Applications may interpret such values as protocol errors.


use http::StatusCode;

assert_eq!(StatusCode::from_u16(200).unwrap(), StatusCode::OK);
assert_eq!(StatusCode::NOT_FOUND.as_u16(), 404);


impl StatusCode[src]

pub fn from_u16(src: u16) -> Result<StatusCode, InvalidStatusCode>[src]

Converts a u16 to a status code.

The function validates the correctness of the supplied u16. It must be greater or equal to 100 and less than 1000.


use http::StatusCode;

let ok = StatusCode::from_u16(200).unwrap();
assert_eq!(ok, StatusCode::OK);

let err = StatusCode::from_u16(99);

pub fn from_bytes(src: &[u8]) -> Result<StatusCode, InvalidStatusCode>[src]

Converts a &u8 to a status code

pub fn as_u16(&self) -> u16[src]

Returns the u16 corresponding to this StatusCode.


This is the same as the From<StatusCode> implementation, but included as an inherent method because that implementation doesn’t appear in rustdocs, as well as a way to force the type instead of relying on inference.


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

pub fn as_str(&self) -> &str[src]

Returns a &str representation of the StatusCode

The return value only includes a numerical representation of the status code. The canonical reason is not included.


let status = http::StatusCode::OK;
assert_eq!(status.as_str(), "200");

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

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 and HTTP/3.0 the reason phrase is abolished from transmission, and so this canonical reason phrase really is the only reason phrase you’ll find.


let status = http::StatusCode::OK;
assert_eq!(status.canonical_reason(), Some("OK"));

pub fn is_informational(&self) -> bool[src]

Check if status is within 100-199.

pub fn is_success(&self) -> bool[src]

Check if status is within 200-299.

pub fn is_redirection(&self) -> bool[src]

Check if status is within 300-399.

pub fn is_client_error(&self) -> bool[src]

Check if status is within 400-499.

pub fn is_server_error(&self) -> bool[src]

Check if status is within 500-599.
