Associated Types

type Item

The type being iterated over.

type Error

The error type.

Required methods

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

Advances the iterator and returns the next value.

Returns Ok(None) when iteration is finished.

The behavior of calling this method after a previous call has returned Ok(None) or Err is implemenetation defined.

Provided methods

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

Returns bounds on the remaining length of the iterator.

Specifically, the first half of the returned tuple is a lower bound and the second half is an upper bound.

For the upper bound, None indicates that the upper bound is either unknown or larger than can be represented as a usize.

Both bounds assume that all remaining calls to next succeed. That is, next could return an Err in fewer calls than specified by the lower bound.

The default implementation returns (0, None), which is correct for any iterator.

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

Consumes the iterator, returning the number of remaining items.

fn last(self) -> Result<Option<Self::Item>, Self::Error> where
    Self: Sized, 

Returns the last element of the iterator.

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

Returns the nth element of the iterator.

fn step_by(self, step: usize) -> StepBy<Self> where
    Self: Sized, 

Returns an iterator starting at the same point, but stepping by the given amount at each iteration.

Panics

Panics if step is 0.

fn chain<I>(self, it: I) -> Chain<Self, I> where
    I: IntoFallibleIterator<Item = Self::Item, Error = Self::Error>,
    Self: Sized, 

Returns an iterator which yields the elements of this iterator followed by another.

fn zip<I>(self, o: I) -> Zip<Self, I::IntoFallibleIter> where
    Self: Sized,
    I: IntoFallibleIterator<Error = Self::Error>, 

Returns an iterator that yields pairs of this iterator's and another iterator's values.

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

Returns an iterator which applies a fallible transform to the elements of the underlying iterator.

fn for_each<F>(self, f: F) -> Result<(), Self::Error> where
    Self: Sized,
    F: FnMut(Self::Item) -> Result<(), Self::Error>, 

Calls a fallible closure on each element of an iterator.

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

Returns an iterator which uses a predicate to determine which values should be yielded. The predicate may fail; such failures are passed to the caller.

fn filter_map<B, F>(self, f: F) -> FilterMap<Self, F> where
    Self: Sized,
    F: FnMut(Self::Item) -> Result<Option<B>, Self::Error>, 

Returns an iterator which both filters and maps. The closure may fail; such failures are passed along to the consumer.

fn enumerate(self) -> Enumerate<Self> where
    Self: Sized, 

Returns an iterator which yields the current iteration count as well as the value.

fn peekable(self) -> Peekable<Self> where
    Self: Sized, 

Returns an iterator that can peek at the next element without consuming it.

fn skip_while<P>(self, predicate: P) -> SkipWhile<Self, P> where
    Self: Sized,
    P: FnMut(&Self::Item) -> Result<bool, Self::Error>, 

Returns an iterator that skips elements based on a predicate.

fn take_while<P>(self, predicate: P) -> TakeWhile<Self, P> where
    Self: Sized,
    P: FnMut(&Self::Item) -> Result<bool, Self::Error>, 

Returns an iterator that yields elements based on a predicate.

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

Returns an iterator which skips the first n values of this iterator.

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

Returns an iterator that yields only the first n values of this iterator.

fn scan<St, B, F>(self, initial_state: St, f: F) -> Scan<Self, St, F> where
    Self: Sized,
    F: FnMut(&mut St, Self::Item) -> Result<Option<B>, Self::Error>, 

Returns an iterator which applies a stateful map to values of this iterator.

fn flat_map<U, F>(self, f: F) -> FlatMap<Self, U, F> where
    Self: Sized,
    U: IntoFallibleIterator<Error = Self::Error>,
    F: FnMut(Self::Item) -> Result<U, Self::Error>, 

Returns an iterator which maps this iterator's elements to iterators, yielding those iterators' values.

fn flatten(self) -> Flatten<Self> where
    Self: Sized,
    Self::Item: IntoFallibleIterator<Error = Self::Error>, 

Returns an iterator which flattens an iterator of iterators, yielding those iterators' values.

fn fuse(self) -> Fuse<Self> where
    Self: Sized, 

Returns an iterator which yields this iterator's elements and ends after the first Ok(None).

The behavior of calling next after it has previously returned Ok(None) is normally unspecified. The iterator returned by this method guarantees that Ok(None) will always be returned.

fn inspect<F>(self, f: F) -> Inspect<Self, F> where
    Self: Sized,
    F: FnMut(&Self::Item) -> Result<(), Self::Error>, 

Returns an iterator which passes each element to a closure before returning it.

Applies a function over the elements of the iterator, producing a single final value.
