Struct rama::http::StatusCode
pub struct StatusCode(/* private fields */);
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§
§impl StatusCode
impl StatusCode
pub fn from_u16(src: u16) -> Result<StatusCode, InvalidStatusCode>
pub fn from_u16(src: u16) -> Result<StatusCode, InvalidStatusCode>
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());
pub fn from_bytes(src: &[u8]) -> Result<StatusCode, InvalidStatusCode>
pub fn from_bytes(src: &[u8]) -> Result<StatusCode, InvalidStatusCode>
Converts a &u8 to a status code
pub fn as_u16(&self) -> u16
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 = http::StatusCode::OK;
assert_eq!(status.as_u16(), 200);
pub fn as_str(&self) -> &str
pub fn as_str(&self) -> &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 = http::StatusCode::OK;
assert_eq!(status.as_str(), "200");
pub fn canonical_reason(&self) -> Option<&'static str>
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 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"));
pub fn is_informational(&self) -> bool
pub fn is_informational(&self) -> bool
Check if status is within 100-199.
pub fn is_success(&self) -> bool
pub fn is_success(&self) -> bool
Check if status is within 200-299.
pub fn is_redirection(&self) -> bool
pub fn is_redirection(&self) -> bool
Check if status is within 300-399.
pub fn is_client_error(&self) -> bool
pub fn is_client_error(&self) -> bool
Check if status is within 400-499.
pub fn is_server_error(&self) -> bool
pub fn is_server_error(&self) -> bool
Check if status is within 500-599.
