source · [−]pub struct Map<I, F> { /* private fields */ }Expand description
An iterator that maps value of another stream with a function.
Trait Implementations
sourceimpl<I, F, B, Fut> Iterator for Map<I, F>where
I: Iterator,
F: FnMut(I::Item) -> Fut,
Fut: Future<Output = B>,
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
type Item = B
The type of the elements being iterated over.
sourceasync fn next(&mut self) -> Option<Self::Item>
async fn next(&mut self) -> Option<Self::Item>
Advances the iterator and returns the next value.
sourcefn size_hint(&self) -> (usize, Option<usize>)
fn size_hint(&self) -> (usize, Option<usize>)
Returns the bounds on the remaining length of the iterator.
sourcefn map<B, F>(self, f: F) -> Map<Self, F>where
Self: Sized,
F: FnMut(Self::Item) -> B,
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.
sourceasync fn collect<B: FromIterator<Self::Item>>(self) -> Bwhere
Self: Sized,
async fn collect<B: FromIterator<Self::Item>>(self) -> Bwhere
Self: Sized,
Transforms an iterator into a collection.
