Struct CloneIterator

pub struct CloneIterator<I>(/* private fields */);

Specialized helper struct to allow adapting any Iterator into a Join.

Join requires the underlying object to be &T: IntoIterator, so that it can be iterated over when formatting via Display. This works fine for collection types like Vec, but it doesn’t work for arbitrary iterators. However, because many iterators are cheaply clonable (because they often just contain a reference to the underlying sequence), we can use this adapter to create an &T: IntoIterator type which can be displayed by Join.

Trait Implementations

impl<I: Clone> Clone for CloneIterator<I>

fn clone(&self) -> CloneIterator<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Debug> Debug for CloneIterator<I>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, I: Iterator + Clone> IntoIterator for &'a CloneIterator<I>

fn into_iter(self) -> Self::IntoIter

Create a referential iterator by cloning the underlying iterator. Note that this will have the same Item type as the underlying iterator, rather than references to those items.

type IntoIter = I

Which kind of iterator are we turning this into?

type Item = <I as Iterator>::Item

The type of the elements being iterated over.

impl<I: Iterator> IntoIterator for CloneIterator<I>

fn into_iter(self) -> Self::IntoIter

Convert the adapter back into the underlying iterator.

type IntoIter = I

Which kind of iterator are we turning this into?

type Item = <I as Iterator>::Item

The type of the elements being iterated over.

impl<I: PartialEq> PartialEq for CloneIterator<I>

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
