Struct predicates::BoxPredicate [−][src]
Predicate
that wraps another Predicate
as a trait object, allowing
sized storage of predicate types.
Implementations
impl<Item> BoxPredicate<Item> where
Item: ?Sized,
[src]
Item: ?Sized,
pub fn new<P: Predicate<Item>>(inner: P) -> BoxPredicate<Item> where
P: Send + Sync + 'static,
[src]
P: Send + Sync + 'static,
Creates a new BoxPredicate
, a wrapper around a dynamically-dispatched
Predicate
type with useful trait impls.
