Struct AccessControlAllowOrigin 

pub struct AccessControlAllowOrigin(/* private fields */);

Access-Control-Allow-Origin header, as defined on mdn.

The Access-Control-Allow-Origin header indicates whether a resource can be shared based by returning the value of the Origin request header, *, or null in the response.

ABNF

Access-Control-Allow-Origin = "Access-Control-Allow-Origin" ":" origin-list-or-null | "*"

Example values

• null
• *
• http://google.com/

Examples

use rama_http_headers::AccessControlAllowOrigin;
use std::convert::TryFrom;

let any_origin = AccessControlAllowOrigin::ANY;
let null_origin = AccessControlAllowOrigin::NULL;
let origin = AccessControlAllowOrigin::try_from("http://web-platform.test:8000");

Returns the origin if there’s one specified.

pub fn try_from_origin_header_value( header_value: &HeaderValue, ) -> Option<AccessControlAllowOrigin>

Trait Implementations

impl Clone for AccessControlAllowOrigin

fn clone(&self) -> AccessControlAllowOrigin

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AccessControlAllowOrigin

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for AccessControlAllowOrigin

impl Hash for AccessControlAllowOrigin

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl HeaderDecode for AccessControlAllowOrigin

fn decode<'i, I>(values: &mut I) -> Result<AccessControlAllowOrigin, Error>

where I: Iterator<Item = &'i HeaderValue>,

Decode this type from an iterator of HeaderValues.

impl HeaderEncode for AccessControlAllowOrigin

fn encode<E>(&self, values: &mut E)

where E: Extend<HeaderValue>,

Encode this type to a HeaderValue, and add it to a container which has HeaderValue type as each element.

fn encode_to_value(&self) -> Option<HeaderValue>

Encode this header to HeaderValue.

impl PartialEq for AccessControlAllowOrigin

fn eq(&self, other: &AccessControlAllowOrigin) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for AccessControlAllowOrigin

type Error = Error

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<AccessControlAllowOrigin, Error>

Performs the conversion.

impl TypedHeader for AccessControlAllowOrigin

fn name() -> &'static HeaderName

The name of this header.
