# Struct actix_web::http::StatusCode[−][src]

    pub struct StatusCode(_);

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

This type contains constants for all common status codes. It allows status codes in the range [100, 599].

IANA maintain the Hypertext Transfer Protocol (HTTP) Status Code Registry which is the source for this enum (with one exception, 418 I'm a teapot, which is inexplicably not in the register).

# 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());

## Methods

###

`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 but less than 600.

# 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>`

[src]

Converts a &u8 to a status code

####

`pub fn as_u16(&self) -> u16`

[src]

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`

[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.

# Example

    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 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`

[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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
