Struct tower_http::cors::AllowOrigin

source · [−]

pub struct AllowOrigin(_);

Available on crate feature cors only.

Expand description

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

See CorsLayer::allow_origin for more details.

Implementations

source

impl AllowOrigin

source

pub fn any() -> Self

Allow any origin by sending a wildcard (*)

See CorsLayer::allow_origin for more details.

source

pub fn exact(origin: HeaderValue) -> Self

Set a single allowed origin

See CorsLayer::allow_origin for more details.

source

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

Set multiple allowed origins

See CorsLayer::allow_origin for more details.

source

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.

source

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.
