Struct predicates::predicate::EqPredicate

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

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: Debug> Debug for EqPredicate<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<T> Predicate for EqPredicate<T> where
    T: PartialEq, 

type Item = T

The type that this Predicate will accept for evaluating.

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

Execute this Predicate against variable, returning the resulting boolean.

fn and<B>(self, other: B) -> AndPredicate<Self, B> where
    B: Predicate<Item = Self::Item>,
    Self: Sized, 

Compute the logical AND of two Predicate results, returning the result.

fn or<B>(self, other: B) -> OrPredicate<Self, B> where
    B: Predicate<Item = Self::Item>,
    Self: Sized, 

Compute the logical OR of two Predicate results, returning the result.

fn not(self) -> NotPredicate<Self> where
    Self: Sized, 

Compute the logical NOT of a Predicate, returning the result.

fn boxed(self) -> BoxPredicate<Self::Item> where
    Self: Sized + Send + Sync + 'static, 

Returns a BoxPredicate wrapper around this Predicate type.
