Struct actix_http::http::StatusCode[][src]

pub struct StatusCode(_);
Expand description

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 http::StatusCode;

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

Implementations

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 http::StatusCode;

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

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

Converts a &u8 to a status code

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

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

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.

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

Check if status is within 100-199.

Check if status is within 200-299.

Check if status is within 300-399.

Check if status is within 400-499.

Check if status is within 500-599.
