Struct predicates::ord::EqPredicate

pub struct EqPredicate<T> { /* private fields */ }

Predicate that returns true if variable matches the pre-defined Eq value, otherwise returns false.

This is created by the predicate::{eq, ne} functions.

Trait Implementations

impl<T: Clone> Clone for EqPredicate<T>

fn clone(&self) -> EqPredicate<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for EqPredicate<T>

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

Formats the value using the given formatter.

impl<T> Display for EqPredicate<T>where
    T: Debug,

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq<EqPredicate<T>> for EqPredicate<T>

fn eq(&self, other: &EqPredicate<T>) -> 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<P, T> Predicate<P> for EqPredicate<T>where
    T: Borrow<P> + Debug,
    P: Debug + PartialEq + ?Sized,

fn eval(&self, variable: &P) -> bool

Execute this Predicate against variable, returning the resulting boolean.

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

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

impl<T> PredicateReflection for EqPredicate<T>where
    T: Debug,

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

Parameters of the current Predicate.

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

Nested Predicates of the current Predicate.
