Struct predicates::ord::EqPredicate

pub struct EqPredicate<T>
where
    T: Debug + PartialEq,
{ /* 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 for EqPredicate<T>

where T: Debug + PartialEq + Clone,

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 for EqPredicate<T>

where T: Debug + PartialEq + Debug,

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

Formats the value using the given formatter.

impl<T> Display for EqPredicate<T>

where T: Debug + PartialEq,

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

Formats the value using the given formatter.

impl<T> PartialEq for EqPredicate<T>

where T: Debug + PartialEq + PartialEq,

fn eq(&self, other: &EqPredicate<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'a, T> Predicate<T> for EqPredicate<&'a T>

where T: Debug + PartialEq + ?Sized,

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

Execute this Predicate against variable, returning the resulting boolean.

fn find_case<'b>(&'b self, expected: bool, variable: &T) -> Option<Case<'b>>

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

impl<T> Predicate<T> for EqPredicate<T>

where T: Debug + PartialEq,

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

Execute this Predicate against variable, returning the resulting boolean.

fn find_case<'a>(&'a self, expected: bool, variable: &T) -> 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 + PartialEq,

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

Parameters of the current Predicate.

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

Nested Predicates of the current Predicate.

impl<T> Copy for EqPredicate<T>

where T: Debug + PartialEq + Copy,

impl<T> Eq for EqPredicate<T>

where T: Debug + PartialEq + Eq,

impl<T> StructuralPartialEq for EqPredicate<T>

where T: Debug + PartialEq,
