Trait Implementations

impl<T: Spliterator> Spliterator for CostMul<T>

type Item = T::Item

The item this iterator produces.

type Base = Hide<CostMul<T::Base>>

The splittable base data which this consists of.

type Consumer = CostMulConsumer<T::Consumer>

A consumer which can act as an ad-hoc iterator adapter chain while being shared across threads.

fn destructure(self) -> (Self::Base, Self::Consumer)

Destructure this iterator into a splittable base and a shareable consumer of that base.

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

A lower bound and optional upper bound on the size of this iterator.

fn cloned<'a, T: 'a + Clone>(self) -> Cloned<Self> where
    Self: Spliterator<Item = &'a T>, 

Clone the items of this iterator to get owned copies.

fn enumerate(self) -> Enumerate<Self>

Enumerate items by their index.

fn filter<F: Sync>(self, pred: F) -> Filter<Self, F> where
    F: Fn(&Self::Item) -> bool, 

Filter items by some predicate.

fn flat_map<U, F: Sync>(self, flat_map: F) -> FlatMap<Self, F> where
    U: IntoIterator,
    F: Fn(Self::Item) -> U, 

Produce an iterator for each element, and then yield the elements of those iterators.

fn map<F: Sync, U>(self, map: F) -> Map<Self, F> where
    F: Fn(Self::Item) -> U, 

Map the items of this iterator to another type using the supplied function.

fn zip<B: IntoSpliterator>(self, other: B) -> Zip<Self, B::SplitIter>

Zip this iterator with another, combining their items in a tuple.

fn any<P: Sync>(self, spawner: &Spawner, pred: P) -> bool where
    P: Fn(Self::Item) -> bool, 

Whether any of the elements fulfill the supplied predicate.

fn all<P: Sync>(self, spawner: &Spawner, pred: P) -> bool where
    P: Fn(Self::Item) -> bool, 

Whether all of the elements fulfill the supplied predicate.

fn for_each<F>(self, spawner: &Spawner, f: F) where
    F: Sync + Fn(Self::Item), 

Consume this iterator, performing an action for each item.

fn collect<T: Send>(self, spawner: &Spawner) -> T where
    Self::Item: Send,
    T: FromIterator<Self::Item> + Combine + Send, 

Collect the items of this iterator into a combinable collection.

fn fold<F: Sync>(
    self,
    spawner: &Spawner,
    initial: Self::Item,
    folder: F
) -> Self::Item where
    F: Folder<Self::Item>,
    Self::Item: Send, 

Fold the items of the iterator together with the given operation and initial state.

fn with_cost_mul(self, mul: f32) -> CostMul<Self>

Uses a cost multiplier for this iterator.

impl<T: ExactSizeSpliterator> ExactSizeSpliterator for CostMul<T>

fn size(&self) -> usize

Get the number of elements in this iterator.

impl<T: Clone> Clone for CostMul<T>

fn clone(&self) -> CostMul<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
