Modules

Structs

ArrayChunks An iterator over N elements of the iterator at a time.
ByRefSized Like Iterator::by_ref, but requiring Sized so it can forward generics.
Chain An iterator that links two iterators together, in a chain.
Cloned An iterator that clones the elements of an underlying iterator.
Copied An iterator that copies the elements of an underlying iterator.
Cycle An iterator that repeats endlessly.
Enumerate An iterator that yields the current count and the element during iteration.
Filter An iterator that filters the elements of iter with predicate.
FilterMap An iterator that uses f to both filter and map elements from iter.
FlatMap An iterator that maps each element to an iterator, and yields the elements of the produced iterators.
Flatten An iterator that flattens one level of nesting in an iterator of things that can be turned into iterators.
Fuse An iterator that yields None forever after the underlying iterator yields None once.
GenericShunt An iterator adapter that produces output as long as the underlying iterator produces values where Try::branch says to ControlFlow::Continue.
Inspect An iterator that calls a function with a reference to each element before yielding it.
Intersperse An iterator adapter that places a separator between all elements.
IntersperseWith An iterator adapter that places a separator between all elements.
Map An iterator that maps the values of iter with f.
MapWhile An iterator that only accepts elements while predicate returns Some(_).
MapWindows An iterator over the mapped windows of another iterator.
Peekable An iterator with a peek() that returns an optional reference to the next element.
Rev A double-ended iterator with the direction inverted.
Scan An iterator to maintain state while iterating another iterator.
Skip An iterator that skips over n elements of iter.
SkipWhile An iterator that rejects elements while predicate returns true.
StepBy An iterator for stepping iterators by a custom amount.
Take An iterator that only iterates over the first n iterations of iter.
TakeWhile An iterator that only accepts elements while predicate returns true.
Zip An iterator that iterates two other iterators simultaneously.

Traits

SourceIter This trait provides transitive access to source-stage in an iterator-adapter pipeline under the conditions that
TrustedRandomAccess An iterator whose items are random-accessible efficiently
TrustedRandomAccessNoCoerce Like TrustedRandomAccess but without any of the requirements / guarantees around coercions to supertypes after __iterator_get_unchecked (they aren’t allowed here!), and without the requirement that subtypes / supertypes implement TrustedRandomAccessNoCoerce.

Functions

chain Converts the arguments to iterators and links them together, in a chain.
try_process Process the given iterator as if it yielded the item's Try::Output type instead. Any Try::Residuals encountered will stop the inner iterator and be propagated back to the overall result.
zip Converts the arguments to iterators and zips them.
