Struct IntoIter 

pub struct IntoIter<A> { /* private fields */ }

An iterator over the value in Some variant of an Option.

The iterator yields one value if the Option is a Some, otherwise none.

This struct is created by the Option::into_iter function.

Trait Implementations

impl<A> Iterator for IntoIter<A>

type Item = A

The type of the elements being iterated over.

fn next(&mut self) -> Option<A>

Advances the iterator and returns the next value.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the iterator.

fn map<B, F>(self, f: F) -> Map<Self, F>

where Self: Sized, F: FnMut(Self::Item) -> B,

Takes a closure and creates an iterator which calls that closure on each element.

fn cloned<'a, T>(self) -> Cloned<Self>

where T: Clone + 'a, Self: Sized + Iterator<Item = &'a T>,

Creates an iterator which clones all of its elements.
