Implementations

impl Cors

pub fn new() -> Self

No origin allowed yet; add some with allow_origin, allow_origins, allow_origin_fn or allow_any_origin

pub fn allow_origin(self, origin: impl Into<String>) -> Self

Allow one origin, written exactly as browsers send it (https://app.example.com, no trailing slash)

pub fn allow_origins<I, S>(self, origins: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

pub fn allow_any_origin(self) -> Self

Allow every origin (Access-Control-Allow-Origin: *). Credentials are never allowed in this mode.

pub fn allow_origin_fn<F>(self, f: F) -> Self

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

Decide per origin, e.g. all subdomains of your own domain

pub fn allow_methods<I>(self, methods: I) -> Self

where I: IntoIterator<Item = Method>,

Methods a cross-origin page may use (default: GET, HEAD, POST, PUT, PATCH, DELETE)

pub fn allow_headers<I, S>(self, headers: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Request headers a cross-origin page may send. Without this call the headers named in the preflight are allowed.

pub fn expose_headers<I, S>(self, headers: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Response headers a cross-origin page may read besides the safelisted ones

pub fn allow_credentials(self) -> Self

Let the page send cookies and Authorization (Access-Control-Allow-Credentials). Ignored together with allow_any_origin.

pub fn max_age(self, max_age: Duration) -> Self

How long browsers may cache a preflight answer (default 10 minutes)

pub fn allow_private_network(self) -> Self

Answer Private Network Access preflights, which public pages send before reaching into a private network (Access-Control-Allow-Private-Network)

Trait Implementations

impl Default for Cors

fn default() -> Self

Returns the “default value” for a type.

impl Middleware for Cors

fn handle<'life0, 'async_trait>( &'life0 self, req: Request, next: Next, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,
