iter

func Empty ¶

func Empty[T any]() Iterator[T]

Empty returns an iterator that never returns anything.

func Flatten ¶

func Flatten[T any](from Iterator[Iterator[T]]) Iterator[T]

Flatten applies a function to all items of the specified iterator, returning an iterator for each item. The resulting iterators are then concatenated into a single iterator.

func FromSlice ¶

func FromSlice[T any](slice []T) Iterator[T]

FromSlice creates a new iterator which returns all items from the slice starting at index 0 until all items are consumed.

func Map ¶

func Map[T any, O any](from Iterator[T], mapFunc func(T) O) Iterator[O]

Map returns a new iterator which applies a function to all items from the input iterator which are subsequently returned.

The mapping function should not mutate the state outside its scope.
