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.

Examples

use axol_http::StatusCode;

assert_eq!(StatusCode::from_u16(200).unwrap(), StatusCode::Ok);
assert_eq!(StatusCode::NotFound.as_u16(), 404);
assert!(StatusCode::Ok.is_success());

Other(u16)

An unknown (invalid) status code. It is a logic error that will do unexpected things if this is initialized to a valid status code.

Implementations

impl StatusCode

pub fn from_repr(discriminant: u16) -> Option<StatusCode>

Try to create Self from the raw representation

impl StatusCode

pub fn from_u16(value: u16) -> Result<Self, StatusCodeError>

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.

Example

use axol_http::StatusCode;

let ok = StatusCode::from_u16(200).unwrap();
assert!(matches!(ok, StatusCode::Ok);

let err = StatusCode::from_u16(99);
assert!(err.is_err());

pub fn as_u16(&self) -> u16

Returns the u16 corresponding to this StatusCode.

Note

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.

Example

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

pub fn as_str(&self) -> &'static str

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.

Example

let status = axol_http::StatusCode::Ok;
assert_eq!(status.as_str(), "200");

pub fn canonical_reason(&self) -> &'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 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.

This is empty for Other or invalid status codes.

Example

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

pub fn is_informational(&self) -> bool

Check if status is within 100-199.

pub fn is_success(&self) -> bool

Check if status is within 200-299.

pub fn is_redirection(&self) -> bool

Check if status is within 300-399.

pub fn is_client_error(&self) -> bool

Check if status is within 400-499.

pub fn is_server_error(&self) -> bool

Check if status is within 500-599.
