Implementations§

source §

impl Builder

source

pub fn allow_credentials(self, allow: bool) -> Self

Sets whether to add the Access-Control-Allow-Credentials header.

source

pub fn allow_method<M>(self, method: M) -> Selfwhere Method: TryFrom<M>,

Adds a method to the existing list of allowed request methods.

Panics

Panics if the provided argument is not a valid http::Method.

source

pub fn allow_methods(self, methods: I) -> Selfwhere I: IntoIterator, Method: TryFrom<I::Item>,

Adds multiple methods to the existing list of allowed request methods.

Panics

Panics if the provided argument is not a valid http::Method.

source

pub fn allow_header<H>(self, header: H) -> Selfwhere HeaderName: TryFrom<H>,

Adds a header to the list of allowed request headers.

Note: These should match the values the browser sends via Access-Control-Request-Headers, e.g. content-type.

Panics

Panics if the provided argument is not a valid http::header::HeaderName.

source

pub fn allow_headers(self, headers: I) -> Selfwhere I: IntoIterator, HeaderName: TryFrom<I::Item>,

Adds multiple headers to the list of allowed request headers.

Note: These should match the values the browser sends via Access-Control-Request-Headers, e.g.content-type.

Panics

Panics if any of the headers are not a valid http::header::HeaderName.

source

pub fn expose_header<H>(self, header: H) -> Selfwhere HeaderName: TryFrom<H>,

Adds a header to the list of exposed headers.

Panics

Panics if the provided argument is not a valid http::header::HeaderName.

source

pub fn expose_headers(self, headers: I) -> Selfwhere I: IntoIterator, HeaderName: TryFrom<I::Item>,

Adds multiple headers to the list of exposed headers.

Panics

Panics if any of the headers are not a valid http::header::HeaderName.

source

pub fn allow_any_origin(self) -> Self

Sets that any Origin header is allowed.

Warning

This can allow websites you didn’t intend to access this resource, it is usually better to set an explicit list.

source

pub fn allow_origin(self, origin: impl IntoOrigin) -> Self

Add an origin to the existing list of allowed Origins.

Panics

Panics if the provided argument is not a valid Origin.

source

pub fn allow_origins(self, origins: I) -> Selfwhere I: IntoIterator, I::Item: IntoOrigin,

Add multiple origins to the existing list of allowed Origins.

Panics

Panics if the provided argument is not a valid Origin.

source

pub fn max_age(self, seconds: impl Seconds) -> Self

Sets the Access-Control-Max-Age header.

Example

use std::time::Duration;
use warp::Filter;

let cors = warp::cors()
    .max_age(30) // 30u32 seconds
    .max_age(Duration::from_secs(30)); // or a Duration

source

pub fn build(self) -> Cors

Builds the Cors wrapper from the configured settings.

This step isn’t required, as the Builder itself can be passed to Filter::with. This just allows constructing once, thus not needing to pay the cost of “building” every time.
