check o returns true if o is an iterator.

next i returns the next value from the iteration i. If there are no remaining values, returns None. Wrapper for PyIter_Next.

iter f i iteratively calls f v with all the remaining values of the iteration i.

to_list i returns the list of all the remaining values from the iteration i.

to_list_map f i returns the list of the results of f applied to all the remaining values from the iteration i. to_list_map f s is equivalent to List.map f (to_list s) but is tail-recursive and f is applied to the elements of s in the reverse order.

of_seq s returns an interator that iterates over the values of the sequence s.

of_seq_map f s returns an interator that iterates over the results of f applied to the values of the sequence s. Py.Iter.of_seq_map f s is equivalent to Py.Iter.of_seq (Seq.map f s).

to_seq i returns the sequence of the values from the iteration i. The Python iteration is consumed while the sequence is browsed. Values are memoized, so that the sequence can be browsed many times.

to_seq_map f i returns the sequence of the results of f applied to the values from the iteration i. The Python iteration is consumed while the sequence is browsed. Values are memoized, so that the sequence can be browsed many times.

unsafe_to_seq i returns the sequence of the values from the iteration i. The Python iteration is consumed while the sequence is browsed. Warning: values are not memoized, so that the sequence can be browsed only once.

unsafe_to_seq_map f i returns the sequence of the results of f applied to the values from the iteration i. The Python iteration is consumed while the sequence is browsed. Warning: values are not memoized, so that the sequence can be browsed only once.

of_list l returns an interator that iterates over the values of the list l.

of_list_map f l returns an interator that iterates over the results of f applied to the values of the list l. Py.Iter.of_list_map f s is equivalent to Py.Iter.of_list (List.map f s) but is tail-recursive.

fold_left f v i returns (f (...(f v i1)...) in) where i1, ..., in are the remaining values from the iteration i.

fold_right f i v returns (f i1 (...(f v in)...) where i1, ..., in are the remaining values from the iteration i. This function is not tail-recursive.

for_all p i checks if p holds for all the remaining values from the iteration i.

exists p i checks if p holds for at least one of the remaining values from the iteration i.

create next returns an iterator that calls next.

Wrapper for PySeqIter_New

Wrapper for PyCallIter_New

create_call next returns an iterator that calls next. The difference with create is that this uses PyCallIter_New rather than creating an object and use the __next__ method.
