Trait async_iterator::Iterator

pub trait Iterator {
    type Item;

    fn next(&mut self) -> impl Future<Output = Option<Self::Item>>;

    fn size_hint(&self) -> (usize, Option<usize>) { ... }
    fn map<B, F>(self, f: F) -> Map<Self, F>
    where
        Self: Sized,

    { ... }
    async fn collect<B: FromIterator<Self::Item>>(self) -> B
    where
        Self: Sized,
    { ... }
}

An interface for dealing with iterators.

Required Associated Types

type Item

The type of the elements being iterated over.

Required Methods

fn next(&mut self) -> impl Future<Output = Option<Self::Item>>

Advances the iterator and returns the next value.

Provided Methods

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

Returns the bounds on the remaining length of the iterator.

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

Takes a closure and creates an iterator which calls that closure on each element.

async fn collect<B: FromIterator<Self::Item>>(self) -> Bwhere
    Self: Sized,

Transforms an iterator into a collection.

Implementors

impl<I, F, B, Fut> Iterator for Map<I, F>where
    I: Iterator,
    F: FnMut(I::Item) -> Fut,
    Fut: Future<Output = B>,

type Item = B
