SizedIter

class guppylang.std.iter.SizedIter

A wrapper around an iterator type L promising that the iterator will yield exactly n values.

Annotating an iterator with an incorrect size is undefined behaviour.

classmethod __class_getitem__(item: Any) → type

__iter__() → SizedIter[L, n]

Dummy implementation making sized iterators iterable themselves.

static __new__(iterator: L @ owned) → SizedIter[L, n]

Casts an iterator into a SizedIter.

unwrap_iter() → L

Extracts the actual iterator.
