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

Available on crate feature cors only.

Holds configuration for how to set the Access-Control-Allow-Origin header.

See CorsLayer::allow_origin for more details.

Implementations

impl AllowOrigin

pub fn any() -> Self

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) -> Self

where 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) -> Self

where F: Fn(&HeaderValue, &RequestParts) -> bool + Send + Sync + 'static,

Set the allowed origins from a predicate

See CorsLayer::allow_origin for more details.

pub fn async_predicate<F, Fut>(f: F) -> Self

where F: FnOnce(HeaderValue, &RequestParts) -> Fut + Send + Sync + 'static + Clone, Fut: Future<Output = bool> + Send + 'static,

Set the allowed origins from an async 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.
