A fallible, streaming iterator.

Associated Types

type Item: ?Sized

The type being iterated over.

type Error

The error type of iteration.

Required Methods

fn advance(&mut self) -> Result<(), Self::Error>

Advances the iterator to the next position.

Iterators start just before the first item, so this method should be called before get when iterating.

The behavior of calling this method after get has returned None, or after this method has returned an error is unspecified.

fn get(&self) -> Option<&Self::Item>

Returns the current element.

The behavior of calling this method before any calls to advance is unspecified.

Provided Methods

fn next(&mut self) -> Result<Option<&Self::Item>, Self::Error>

Advances the iterator, returning the next element.

The default implementation simply calls advance followed by get.

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

Returns bounds on the number of remaining elements in the iterator.

fn all<F>(&mut self, f: F) -> Result<bool, Self::Error> where
    F: FnMut(&Self::Item) -> bool, 

Determines if all elements of the iterator satisfy a predicate.

fn any<F>(&mut self, f: F) -> Result<bool, Self::Error> where
    F: FnMut(&Self::Item) -> bool, 

Determines if any elements of the iterator satisfy a predicate.

fn by_ref(&mut self) -> &mut Self

Borrows an iterator, rather than consuming it.

This is useful to allow the application of iterator adaptors while still retaining ownership of the original adaptor.

fn count(self) -> Result<usize, Self::Error>

Returns the number of remaining elements in the iterator.

fn filter<F>(self, f: F) -> Filter<Self, F> where
    F: FnMut(&Self::Item) -> bool, 

Returns an iterator which filters elements by a predicate.

fn find<F>(&mut self, f: F) -> Result<Option<&Self::Item>, Self::Error> where
    F: FnMut(&Self::Item) -> bool, 

Returns the first element of the iterator which satisfies a predicate.

fn fuse(self) -> Fuse<Self>

Returns an iterator which is well-behaved at the beginning and end of iteration.

fn map<F, B>(self, f: F) -> Map<Self, F, B> where
    F: FnMut(&Self::Item) -> B, 

Returns an iterator which applies a transform to elements.

fn map_ref<F, B>(self, f: F) -> MapRef<Self, F> where
    B: ?Sized,
    F: Fn(&Self::Item) -> &B, 

Returns an iterator which applies a transform to elements.

Unlike map, the the closure provided to this method returns a reference into the original value.

fn map_err<F, B>(self, f: F) -> MapErr<Self, F> where
    F: Fn(Self::Error) -> B, 

Returns an iterator that applies a transform to errors.

fn nth(&mut self, n: usize) -> Result<Option<&Self::Item>, Self::Error>

Returns the nth element of the iterator.

fn position<F>(&mut self, f: F) -> Result<Option<usize>, Self::Error> where
    F: FnMut(&Self::Item) -> bool, 

Returns the position of the first element matching a predicate.

fn skip(self, n: usize) -> Skip<Self>

Returns an iterator which skips the first n elements.

fn skip_while<F>(self, f: F) -> SkipWhile<Self, F> where
    F: FnMut(&Self::Item) -> bool, 

Returns an iterator which skips the first sequence of elements matching a predicate.

fn take(self, n: usize) -> Take<Self>

Returns an iterator which only returns the first n elements.

fn take_while<F>(self, f: F) -> TakeWhile<Self, F> where
    F: FnMut(&Self::Item) -> bool, 

Returns an iterator which only returns the first sequence of elements matching a predicate.
