Struct AllowOrigin

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

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() -> AllowOrigin

Allow any origin by sending a wildcard (*)

See CorsLayer::allow_origin for more details.

pub fn exact(origin: HeaderValue) -> AllowOrigin

Set a single allowed origin

See CorsLayer::allow_origin for more details.

pub fn list<I>(origins: I) -> AllowOrigin

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) -> AllowOrigin

where F: Fn(&HeaderValue, &Parts) -> 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) -> AllowOrigin

where F: FnOnce(HeaderValue, &Parts) -> 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() -> AllowOrigin

Allow any origin, by mirroring the request origin

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

See CorsLayer::allow_origin for more details.
