Structs

Iter

🌐 🔄 Iterator-related namespaced operations.

IterChain

🔄 core An iterator that links two iterators together, in a chain.

IterCloned

🔄 core An iterator that clones the elements of an underlying iterator.

IterCopied

🔄 core An iterator that copies the elements of an underlying iterator.

IterCycle

🔄 core An iterator that repeats endlessly.

IterEmpty

🔄 core An iterator that yields nothing.

IterEnumerate

🔄 core An iterator that yields the current count and the element during iteration.

IterFilter

🔄 core An iterator that filters the elements of iter with predicate.

IterFilterMap

🔄 core An iterator that uses f to both filter and map elements from iter.

IterFlatMap

🔄 core An iterator that maps each element to an iterator, and yields their elements.

IterFlatten

🔄 core An iterator that flattens one level of nesting in an iterator of iterables.

IterFromFn

🔄 core An iterator where each iteration calls a closure F: FnMut() -> Option<T>.

IterFuse

🔄 core An iterator that yields None forever after the underlying yields None once.

IterInspect

🔄 core An iterator that calls a fn with a reference to each element before yielding it.

IterMap

🔄 core An iterator that maps the values of iter with f.

IterOnce

🔄 core An iterator that yields an element exactly once.

IterOnceWith

🔄 core An iterator that yields a single element A by calling F: FnOnce() -> A.

IterPeekable

🔄 core An iterator with a peek() that returns an optional ref to the next element.

IterRepeat

🔄 core An iterator that repeats an element endlessly.

IterRepeatN

IteratorInto

🔄 core Conversion into an Iterator.

IteratorMultiUnzipdep_itertools

🔄 itertools An iterator that can be unzipped into multiple collections.

IteratorPeekingNextdep_itertools

🔄 itertools An iterator that allows peeking at an element before deciding to accept it.

IteratorProduct

🔄 core Represents types that can be created by multiplying elements of an iterator.

IteratorSum

🔄 core Represents types that can be created by summing up an iterator.

Itertoolsdep_itertools

🔄 itertools An Iterator blanket impl providing extra adaptors and methods.
