Struct Or

pub struct Or<T, U> { /* private fields */ }

Boolean “or” combinator for predicates. Produced by the bitwise or (|) operator on the base predicates from this module.

Trait Implementations

impl<Rhs, T, U> BitAnd<Rhs> for Or<T, U>

where Self: PredicateReflection, Rhs: PredicateReflection,

type Output = And<Or<T, U>, Rhs>

The resulting type after applying the & operator.

fn bitand(self, rhs: Rhs) -> Self::Output

Performs the & operation.

impl<Rhs, T, U> BitOr<Rhs> for Or<T, U>

where Self: PredicateReflection, Rhs: PredicateReflection,

type Output = Or<Or<T, U>, Rhs>

The resulting type after applying the | operator.

fn bitor(self, rhs: Rhs) -> Self::Output

Performs the | operation.

impl<T: Clone, U: Clone> Clone for Or<T, U>

fn clone(&self) -> Or<T, U>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, U: Debug> Debug for Or<T, U>

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

Formats the value using the given formatter.

impl<T: Display, U: Display> Display for Or<T, U>

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

Formats the value using the given formatter.

impl<T: PartialEq, U: PartialEq> PartialEq for Or<T, U>

fn eq(&self, other: &Or<T, U>) -> 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<T, U, Item: ?Sized> Predicate<Item> for Or<T, U>

where T: Predicate<Item>, U: Predicate<Item>,

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

Execute this Predicate against variable, returning the resulting boolean.

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

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

impl<T: PredicateReflection, U: PredicateReflection> PredicateReflection for Or<T, U>

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, U: Copy> Copy for Or<T, U>

impl<T: Eq, U: Eq> Eq for Or<T, U>

impl<T, U> StructuralPartialEq for Or<T, U>
