Overview ¶
Package itz implements additional utilities for Go iterators.
This library seeks to be aligned with patterns and naming used in the standard library such as the signatures in the `slices` package.

Functions ¶
func Chunk ¶
Chunk is the equivalant of slices.Chunk, but for iterators.
func Concat ¶
Concat composes iterators together in the provided order.
This is similar to Python's `itertools.chain(*iterables)`.
func Filter ¶
Filter returns an iterator yielding all elements that the predicate returns truthy for.
func FlatMap ¶
FlatMap flattens a nested iterator and applies a transformation function.
Friendly reminder: Go is not a functional programming language ;)
func MapE ¶
MapE creates a new iterator with each element transformed by the provided, falable function.
func MapOption ¶
MapOption iterates over a fallable iterator, stopping if an error is returned, but otherwise applies the transformation to each element.
