Struct jobsteal::iter::FlatMap

pub struct FlatMap<T, F> { /* fields omitted */ }

Flat Mapping iterator adapter.

This produces an iterator for each item, and then yields the items of those iterators.

Trait Implementations

impl<T: Spliterator, F, U> Spliterator for FlatMap<T, F> where
    F: Sync + Fn(T::Item) -> U,
    U: IntoIterator, 

type Item = U::Item

The item this iterator produces.

type Base = FlatMapBase<T::Base>

The splittable base data which this consists of.

type Consumer = FlatMap<T::Consumer, F>

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

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

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

Uses a cost multiplier for this iterator.

impl<In: IntoIterator, T: Consumer<In>, F, I> Consumer<FlatMapBase<In>> for FlatMap<T, F> where
    F: Sync + Fn(T::Item) -> I,
    I: IntoIterator, 

type Item = I::Item

fn consume<C: Callback<Self::Item>>(&self, i: FlatMapBase<In>, cb: C) -> C::Out

Consume the iterator, typically by passing it on to the parent consumer along with a callback which will receive a producer of items to transform.

impl<T: Clone, F: Clone> Clone for FlatMap<T, F>

fn clone(&self) -> FlatMap<T, F>

Returns a copy of the value.

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

Performs copy-assignment from source.
