Struct Time 

pub struct Time<I, T>
where
    I: StreamingIterator<Item = T>,
    T: Clone,

impl<I, T> StreamingIterator for Time<I, T>

where I: Sized + StreamingIterator<Item = T>, T: Sized + Clone,

type Item = TimedResult<T>

The type of the elements being iterated over.

fn advance(&mut self)

Advances the iterator to the next element.

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

Returns a reference to the current element of the iterator.

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

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 all<F>(&mut self, f: F) -> bool

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

Determines if all elements of the iterator satisfy a predicate.

fn any<F>(&mut self, f: F) -> bool

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

Determines if any elements of the iterator satisfy a predicate.

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

where Self: Sized,

Borrows an iterator, rather than consuming it.

fn chain<I>(self, other: I) -> Chain<Self, I>

where Self: Sized, I: StreamingIterator<Item = Self::Item>,

Consumes two iterators and returns a new iterator that iterates over both in sequence.

fn cloned(self) -> Cloned<Self>

where Self: Sized, Self::Item: Clone,

Produces a normal, non-streaming, iterator by cloning the elements of this iterator.

fn count(self) -> usize

where Self: Sized,

Consumes the iterator, counting the number of remaining elements and returning it.

fn filter<F>(self, f: F) -> Filter<Self, F>

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

Creates an iterator which uses a closure to determine if an element should be yielded.

fn filter_map<B, F>(self, f: F) -> FilterMap<Self, B, F>

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

Creates an iterator which both filters and maps by applying a closure to elements.

where Self: Sized, J: StreamingIterator, F: FnMut(&Self::Item) -> J,

Creates an iterator which flattens iterators obtained by applying a closure to elements. Note that the returned iterators must be streaming iterators.

fn filter_map_deref<B, F>(self, f: F) -> FilterMapDeref<Self, F>

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

Creates a regular, non-streaming iterator which both filters and maps by applying a closure to elements.

fn find<F>(&mut self, f: F) -> Option<&Self::Item>

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

Returns the first element of the iterator that satisfies the predicate.

fn fuse(self) -> Fuse<Self>

where Self: Sized,

Creates an iterator which is “well behaved” at the beginning and end of iteration.

fn inspect<F>(self, f: F) -> Inspect<Self, F>

where F: FnMut(&Self::Item), Self: Sized,

Call a closure on each element, passing the element on. The closure is called upon calls to advance or advance_back, and exactly once per element regardless of how many times (if any) get is called.

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

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

Creates an iterator which transforms elements of this iterator by passing them to a closure.

fn map_deref<B, F>(self, f: F) -> MapDeref<Self, F>

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

Creates a regular, non-streaming iterator which transforms elements of this iterator by passing them to a closure.

fn map_ref<B, F>(self, f: F) -> MapRef<Self, F>

where Self: Sized, F: Fn(&Self::Item) -> &B, B: ?Sized,

Creates an iterator which transforms elements of this iterator by passing them to a closure.

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

Consumes the first n elements of the iterator, returning the next one.

fn position<F>(&mut self, f: F) -> Option<usize>

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

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

Creates an iterator that skips initial elements matching a predicate.

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

where Self: Sized,

Creates an iterator which only returns the first n elements.

fn take_while<F>(self, f: F) -> TakeWhile<Self, F>

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

Creates an iterator which only returns initial elements matching a predicate.

fn fold<B, F>(self, init: B, f: F) -> B

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