Expand description

A condition to decide whether Request within the given [Context] matches for router or other middleware purposes.

Required Methods§

fn matches(&self, ext: Option<&mut Extensions>, req: &Request) -> bool

returns true on a match, false otherwise

ext is None in case the callee is not interested in collecting potential match metadata gathered during the matching process. An example of this path parameters for an http Uri matcher.

Provided Methods§

fn or<M>(self, other: M) -> impl Matcher<Request>
where Self: Sized, M: Matcher<Request>,

Provide an alternative matcher to match if the current one does not match.

fn and<M>(self, other: M) -> impl Matcher<Request>
where Self: Sized, M: Matcher<Request>,

Add another condition to match on top of the current one.

fn not(self) -> impl Matcher<Request>
where Self: Sized,

Negate the current condition.
