Enum koto_runtime::IsIterable
source · pub enum IsIterable {
NotIterable,
Iterable,
ForwardIterator,
BidirectionalIterator,
}
Expand description
An enum that indicates to the runtime if a KotoObject is iterable
Variants§
NotIterable
The object is not iterable
Iterable
The object is iterable
An iterable object is not itself an iterator, but provides an implementation of KotoObject::make_iterator that is used to make an iterator when one is needed by the runtime.
ForwardIterator
The object is a forward-only iterator
A forward iterator provides an implementation of KotoObject::iterator_next, but not KotoObject::iterator_next_back.
BidirectionalIterator
The object is a bidirectional iterator.
A bidirectional iterator provides an implementation of KotoObject::iterator_next and KotoObject::iterator_next_back.
