Struct Or 

pub struct Or<A, B>(pub A, pub B);

A pattern that matches either of two sub-patterns.

Tuple Fields

0: A

1: B

Trait Implementations

impl<'a, Reference, A, B, D> Pattern<'a, Reference> for Or<A, B>

where Reference: Iterator + Clone + PeekableExt, A: Pattern<'a, Reference, Dest = D>, B: Pattern<'a, Reference, Dest = D>, D: Destination<Reference::Item> + Clone, Reference::Item: Satisfies<<<A as Pattern<'a, Reference>>::Iter as Iterator>::Item> + Satisfies<<<B as Pattern<'a, Reference>>::Iter as Iterator>::Item>,

type Iter = Peekable<Empty<<Reference as Iterator>::Item>>

type Dest = D

fn get_iter(&'a self) -> Self::Iter

Get an iterator over the pattern’s items.

fn consume(&'a self, reference: &mut Reference) -> bool

where Reference::Item: Satisfies<<Self::Iter as Iterator>::Item>,

Consume items from the reference iterator.

fn consume_with_dest( &'a self, reference: &mut Reference, dest: Option<&RefCell<Self::Dest>>, ) -> bool

where Reference::Item: Satisfies<<Self::Iter as Iterator>::Item>,

Consume items from the reference iterator, optionally storing matched items in a destination.

fn get_dest_mut(&self) -> Option<RefMut<'_, Self::Dest>>

Get a mutable reference to the pattern’s internal destination, if any.

fn matches<'s, R>(&'a self, reference: &'s R) -> bool

where R: Iterable<'s, Iter = Reference> + 's, Self::Dest: Destination<Reference::Item>, Reference: PeekableExt, Reference::Item: Satisfies<<Self::Iter as Iterator>::Item>,

Match the pattern against the reference iterator.
