Struct kvarn::cors::AllowList

pub struct AllowList { /* private fields */ }

A CORS allow list which allowes hosts, methods, and headers from a associated path. This is a builder-like struct. Use the add_* methods to add allowed origins, methods, and headers. Multiple allow lists can be added to a Cors instance. See the example at Cors.

Use RuleSet::add to add a rule.

Implementations

impl AllowList

pub fn new(cache_for: Duration) -> Self

Creates a empty CORS allow list with the client cache duration of cache_for.

pub fn add_origin(self, allowed_origin: impl AsRef<str>) -> Self

Allows CORS request from allowed_origin. Note that the scheme (https / http) is sensitive. Use Self::add_origin_uri for a Uri input.

Panics

Panics if allowed_origin is not a valid Uri or if it doesn’t contain a host AND a scheme.

pub fn add_origin_uri(self, allowed_origin: Uri) -> Self

Allows CORS request from allowed_origin. Note that the scheme (https / http) is sensitive.

Panics

Panics if allowed_origin doesn’t contain a host AND a scheme.

pub fn allow_all_origins(self) -> Self

Enables the flag to allow all origins to use the set methods and headers in CORS requests.

pub fn add_method(self, allowed_method: Method) -> Self

Allows the listed origin(s) (added via Self::add_origin) to request using allowed_method.

pub fn allow_all_methods(self) -> Self

Allows all methods.

pub fn add_header(self, allowed_header: HeaderName) -> Self

Allows the listed origin(s) (added via Self::add_origin) to send the allowed_header in the request.

pub fn check( &self, origin: &Uri ) -> Option<(MethodAllowList<'_>, &[HeaderName], Duration)>

Checks if the origin is allowed according to the allow list.

Returns Some if origin is allowed, with the Methods and HeaderNames allowed, with a cache max-age of Duration. Returns None if origin isn’t allowed.
