Struct predicates::boolean::NotPredicate

pub struct NotPredicate<M, Item> where
    M: Predicate<Item>,
    Item: ?Sized,  { /* fields omitted */ }

Predicate that returns a Predicate taking the logical NOT of the result.

This is created by the Predicate::not function.

Methods

impl<M, Item> NotPredicate<M, Item> where     M: Predicate<Item>,     Item: ?Sized,

pub fn new(inner: M) -> NotPredicate<M, Item>

Create a new NotPredicate over predicate inner.
