Struct predicates::boolean::OrPredicate

pub struct OrPredicate<M1, M2, Item> where
    M1: Predicate<Item>,
    M2: Predicate<Item>,
    Item: ?Sized,  { /* fields omitted */ }

Predicate that combines two Predicates, returning the OR of the results.

This is created by the Predicate::or function.
