Struct ExtensionMatcher

pub struct ExtensionMatcher<P, T> { /* private fields */ }

A matcher which allows you to match based on an extension, either by comparing with an extension (ExtensionMatcher::with_const), or using a custom predicate (ExtensionMatcher::with_fn).

Implementations

impl<F, T> ExtensionMatcher<PredicateFn<F, T>, T>

where F: Fn(&T) -> bool + Send + Sync + 'static, T: Clone + Eq + Send + Sync + 'static,

pub fn with_fn(predicate: F) -> Self

Create a new ExtensionMatcher with a predicate F, that will be called using the found T (if one is present), to let it decide whether or not the extension value is a match or not.

impl<T> ExtensionMatcher<PredicateConst<T>, T>

where T: Clone + Eq + Send + Sync + 'static,

pub fn with_const(value: T) -> Self

Create a new ExtensionMatcher with a const value T, that will be Eq-checked to find a match.

Trait Implementations

impl<State, Request, P, T> Matcher<State, Request> for ExtensionMatcher<P, T>

where State: Clone + Send + Sync + 'static, Request: Send + 'static, T: Clone + Send + Sync + 'static, P: ExtensionPredicate<T>,

fn matches( &self, _ext: Option<&mut Extensions>, ctx: &Context<State>, _req: &Request, ) -> bool

returns true on a match, false otherwise

fn or<M>(self, other: M) -> impl Matcher<State, Request>

where Self: Sized, M: Matcher<State, Request>,

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

fn and<M>(self, other: M) -> impl Matcher<State, Request>

where Self: Sized, M: Matcher<State, Request>,

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

fn not(self) -> impl Matcher<State, Request>

where Self: Sized,

Negate the current condition.
