Struct predicates::boolean::NotPredicate

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

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

This is created by the Predicate::not function.

Implementations

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.

Trait Implementations

impl<M, Item> Clone for NotPredicate<M, Item>

where M: Predicate<Item> + Clone, Item: ?Sized + Clone,

fn clone(&self) -> NotPredicate<M, Item>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M, Item> Debug for NotPredicate<M, Item>

where M: Predicate<Item> + Debug, Item: ?Sized + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<M, Item> Display for NotPredicate<M, Item>

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

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<M, Item> PartialEq for NotPredicate<M, Item>

where M: Predicate<Item> + PartialEq, Item: ?Sized + PartialEq,

fn eq(&self, other: &NotPredicate<M, Item>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<M, Item> Predicate<Item> for NotPredicate<M, Item>

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

fn eval(&self, item: &Item) -> bool

Execute this Predicate against variable, returning the resulting boolean.

fn find_case<'a>(&'a self, expected: bool, variable: &Item) -> Option<Case<'a>>

Find a case that proves this predicate as expected when run against variable.

impl<M, Item> PredicateReflection for NotPredicate<M, Item>

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

fn children<'a>(&'a self) -> Box<dyn Iterator<Item = Child<'a>> + 'a>

Nested Predicates of the current Predicate.

fn parameters<'a>(&'a self) -> Box<dyn Iterator<Item = Parameter<'a>> + 'a>

Parameters of the current Predicate.

impl<M, Item> Copy for NotPredicate<M, Item>

where M: Predicate<Item> + Copy, Item: ?Sized + Copy,

impl<M, Item> Eq for NotPredicate<M, Item>

where M: Predicate<Item> + Eq, Item: ?Sized + Eq,

impl<M, Item> StructuralPartialEq for NotPredicate<M, Item>

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