pub struct Status {
pub code: u16,
}Expand description
Structure representing an HTTP status: an integer code.
A Status should rarely be created directly. Instead, an associated
constant should be used; one is declared for every status defined in the
HTTP standard. If a custom status code must be created, note that it is
not possible to set a custom reason phrase.
use rocket::http::Status;
// Create a status from a known constant.
let ok = Status::Ok;
assert_eq!(ok.code, 200);
assert_eq!(ok.reason(), Some("OK"));
let not_found = Status::NotFound;
assert_eq!(not_found.code, 404);
assert_eq!(not_found.reason(), Some("Not Found"));
// Or from a status code: `reason()` returns the phrase when known.
let gone = Status::new(410);
assert_eq!(gone.code, 410);
assert_eq!(gone.reason(), Some("Gone"));
// `reason()` returns `None` when unknown.
let custom = Status::new(599);
assert_eq!(custom.code, 599);
assert_eq!(custom.reason(), None);Responding
To set a custom Status on a response, use a response::status
responder, which enforces correct status-based responses. Alternatively,
respond with (Status, T) where T: Responder, but beware that the
response may be invalid if it requires additional headers.
use rocket::http::Status;
#[get("/")]
fn index() -> (Status, &'static str) {
(Status::NotFound, "Hey, there's no index!")
}(De)serialization
Status is both Serialize and Deserialize, represented as a u16. For
example, Status::Ok (de)serializes from/to 200. Any integer in the
range [100, 600) is allowed to deserialize into a Status.`
use serde::{Serialize, Deserialize};
use rocket::http::Status;
#[derive(Deserialize, Serialize)]
struct Foo {
status: Status,
}Fields§
§code: u16The HTTP status code associated with this status.

sourcepub const fn new(code: u16) -> Status
pub const fn new(code: u16) -> Status
Creates a new Status with code. This should be used only to
construct non-standard HTTP statuses. Use an associated constant for
standard statuses.
Example
Create a custom 299 status:
use rocket::http::Status;
let custom = Status::new(299);
assert_eq!(custom.code, 299);sourcepub const fn class(self) -> StatusClass
pub const fn class(self) -> StatusClass
Returns the class of a given status.
Example
use rocket::http::{Status, StatusClass};
let processing = Status::Processing;
assert_eq!(processing.class(), StatusClass::Informational);
let ok = Status::Ok;
assert_eq!(ok.class(), StatusClass::Success);
let see_other = Status::SeeOther;
assert_eq!(see_other.class(), StatusClass::Redirection);
let not_found = Status::NotFound;
assert_eq!(not_found.class(), StatusClass::ClientError);
let internal_error = Status::InternalServerError;
assert_eq!(internal_error.class(), StatusClass::ServerError);
let custom = Status::new(600);
assert_eq!(custom.class(), StatusClass::Unknown);sourcepub const fn from_code(code: u16) -> Option<Status>
pub const fn from_code(code: u16) -> Option<Status>
Returns a Status given a standard status code code. If code is
not a known status code, None is returned.
Example
Create a Status from a known code:
use rocket::http::Status;
let not_found = Status::from_code(404);
assert_eq!(not_found, Some(Status::NotFound));Create a Status from an unknown code:
use rocket::http::Status;
let unknown = Status::from_code(600);
assert!(unknown.is_none());sourcepub const fn reason(&self) -> Option<&'static str>
pub const fn reason(&self) -> Option<&'static str>
Returns the canonical reason phrase if self corresponds to a
canonical, known status code. Otherwise, returns None.
Example
Reason phrase from a known code:
use rocket::http::Status;
assert_eq!(Status::Created.reason(), Some("Created"));
assert_eq!(Status::new(200).reason(), Some("OK"));Absent phrase from an unknown code:
use rocket::http::Status;
assert_eq!(Status::new(499).reason(), None);sourcepub const fn reason_lossy(&self) -> &'static str
pub const fn reason_lossy(&self) -> &'static str
Returns the canonical reason phrase if self corresponds to a
canonical, known status code, or an unspecified but relevant reason
phrase otherwise.
Example
use rocket::http::Status;
assert_eq!(Status::NotFound.reason_lossy(), "Not Found");
assert_eq!(Status::new(100).reason_lossy(), "Continue");
assert!(!Status::new(699).reason_lossy().is_empty());Trait Implementations§

impl<'r> Responder<'r, 'static> for Status
The response generated by Status depends on the status code itself. The
table below summarizes the functionality:
| Status Code Range | Response |
|---|---|
| [400, 599] | Forwards to catcher for given status. |
| 100, [200, 205] | Empty with status of self. |
| All others. | Invalid. Errors to 500 catcher. |
In short, a client or server error status codes will forward to the
corresponding error catcher, a successful status code less than 206 or
100 responds with any empty body and the given status code, and all other
status code emit an error message and forward to the 500 (internal server
error) catcher.

fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to

This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.

fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific

wrap(), which have the same functionality but are
pithier.
Example
Enable wrapping using .quirk():

fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
