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

pub struct AccessControlRequestMethodMatcher { /* private fields */ }

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.
