Struct ExtensionMatcher

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

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) -> ExtensionMatcher<PredicateFn<F, T>, T>

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) -> ExtensionMatcher<PredicateConst<T>, T>

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