Trait Implementations

impl<I: PopulatedIterator> IntoIterator for Flatten<I>

where I::Item: IntoPopulatedIterator,

type Item = <<I as IntoIterator>::Item as IntoIterator>::Item

The type of the elements being iterated over.

type IntoIter = Flatten<<I as IntoIterator>::IntoIter>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<I: PopulatedIterator> PopulatedIterator for Flatten<I>

where I::Item: IntoPopulatedIterator,

fn next(self) -> (Self::Item, Self::IntoIter)

Advances the iterator and returns the first value and a new iterator to the remaining values.

fn collect<C: FromPopulatedIterator<Self::Item>>(self) -> C

where Self: Sized,

Collects the iterator into a collection. Supports constructing collections that require a populated iterator.

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

where Self: Sized,

Takes a closure and creates an iterator which calls that closure on each element. Preserves the populated property.

fn enumerate(self) -> Enumerate<Self>

where Self: Sized,

Creates an iterator giving the current element count along with the element. Preserves the populated property.

fn zip<J>(self, other: J) -> Zip<Self, J>

where Self: Sized,

Zips this iterator with another iterator to yield a new iterator of pairs. Preserves the populated property.

fn flatten(self) -> Flatten<Self>

where Self: Sized, Self::Item: IntoPopulatedIterator,

Flattens a populated iterator of populated iteratorables into a single iterator. Preserves the populated property.

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

where Self: Sized,

Creates an iterator taking at most n elements from this iterator, where n is non-zero. Preserves the populated property.

fn flat_map<B: IntoPopulatedIterator, F: FnMut(Self::Item) -> B>( self, f: F, ) -> Flatten<Map<Self, F>>

where Self: Sized,

Creates an iterator that works like map, but flattens nested populated structure. Preserves the populated property.

fn max(self) -> Self::Item

where Self::Item: Ord, Self: Sized,

Returns the maximum element of the iterator. Note that unlike the standard library, this method directly returns the maximum element instead of an Option. This is because this method is only available on populated iterators.

fn min(self) -> Self::Item

where Self::Item: Ord, Self: Sized,

Returns the minimum element of the iterator.

fn chain<I: IntoIterator<Item = Self::Item>>( self, other: I, ) -> Chain<Self, I::IntoIter>

where Self: Sized,

Takes self populator and another iteratorable and creates a new iterator over both in sequence. Preserves the populated property.

fn reduce( self, f: impl FnMut(Self::Item, Self::Item) -> Self::Item, ) -> Self::Item

where Self: Sized,

Reduces the iterator to a single value using a closure. Note that unlike the standard library, this method directly returns the reduced value instead of an Option. This is because this method is only available on populated iterators.

fn max_by_key<K: Ord>(self, f: impl FnMut(&Self::Item) -> K) -> Self::Item

where Self: Sized,

Returns the element that gives the maximum value from the specified function. Note that unlike the standard library, this method directly returns the maximum element instead of an Option. This is because this method is only available on populated iterators.

fn max_by( self, compare: impl FnMut(&Self::Item, &Self::Item) -> Ordering, ) -> Self::Item

where Self: Sized,

Returns the element that gives the maximum value with respect to the specified comparison function. Note that unlike the standard library, this method directly returns the maximum element instead of an Option. This is because this method is only available on populated iterators.

fn min_by_key<K: Ord>(self, f: impl FnMut(&Self::Item) -> K) -> Self::Item

where Self: Sized,

Returns the element that gives the minimum value from the specified function. Note that unlike the standard library, this method directly returns the minimum element instead of an Option. This is because this method is only available on populated iterators.

fn min_by( self, compare: impl FnMut(&Self::Item, &Self::Item) -> Ordering, ) -> Self::Item

where Self: Sized,

Returns the element that gives the minimum value with respect to the specified comparison function. Note that unlike the standard library, this method directly returns the minimum element instead of an Option. This is because this method is only available on populated iterators.

fn eq<I: IntoIterator>(self, other: I) -> bool

where Self::Item: PartialEq<I::Item>, Self: Sized,

fn last(self) -> Self::Item

where Self: Sized,

fn rev(self) -> Rev<Self>

where Self: Sized,

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

where Self: Sized,

fn count(self) -> NonZeroUsize

where Self: Sized,
