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>
impl<F, T> ExtensionMatcher<PredicateFn<F, T>, T>
pub fn with_fn(predicate: F) -> ExtensionMatcher<PredicateFn<F, T>, T>
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>
impl<T> ExtensionMatcher<PredicateConst<T>, T>
pub fn with_const(value: T) -> ExtensionMatcher<PredicateConst<T>, T>
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.
