use headers::AccessControlAllowOrigin;
use std::convert::TryFrom;

let any_origin = AccessControlAllowOrigin::ANY;

Trait Implementations

impl Clone for AccessControlAllowOrigin

fn clone(&self) -> AccessControlAllowOrigin

Returns a copy 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

Formats the value using the given formatter.

impl Hash for AccessControlAllowOrigin

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

The name of this header.

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

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

Decode this type from an iterator of HeaderValues.

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

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.
