Allow any origin by sending a wildcard (*)

See CorsLayer::allow_origin for more details.

pub fn exact(origin: HeaderValue) -> Self

Set a single allowed origin

See CorsLayer::allow_origin for more details.

pub fn list<I>(origins: I) -> Selfwhere
    I: IntoIterator<Item = HeaderValue>,

Set multiple allowed origins

See CorsLayer::allow_origin for more details.

Panics

If the iterator contains a wildcard (*).

pub fn predicate<F>(f: F) -> Selfwhere
    F: Fn(&HeaderValue, &RequestParts) -> bool + Send + Sync + 'static,

Set the allowed origins from a predicate

See CorsLayer::allow_origin for more details.

pub fn mirror_request() -> Self

Allow any origin, by mirroring the request origin

This is equivalent to AllowOrigin::predicate(|_, _| true).

See CorsLayer::allow_origin for more details.
