Struct gotham::router::route::matcher::access_control_request_method::AccessControlRequestMethodMatcher

pub struct AccessControlRequestMethodMatcher { /* fields omitted */ }

A route matcher that checks whether the value of the Access-Control-Request-Method header matches the defined value.

Usage:

let matcher = AccessControlRequestMethodMatcher::new(Method::PUT);

// use the matcher for your request
route.options("/foo")
	.extend_route_matcher(matcher)
	.to(|state| {
		// we know that this is a CORS preflight for a PUT request
		let mut res = create_empty_response(&state, StatusCode::NO_CONTENT);
		res.headers_mut().insert(ACCESS_CONTROL_ALLOW_METHODS, "PUT".parse().unwrap());
		(state, res)
	});

Implementations

impl AccessControlRequestMethodMatcher

pub fn new(method: Method) -> Self

Construct a new matcher that matches if the Access-Control-Request-Method header matches method. Note that during matching the method is normalized according to the fetch specification, that is, byte-uppercased. This means that when using a custom method instead of a predefined one, make sure it is uppercased or this matcher will never succeed.
