func Batch ¶ added in v0.3.0

func Batch[T any](it iter.Seq[T], n int) iter.Seq[[]T]

Batch iterator into groups of n elements. Returned slices is reused between iterators. If caller needs a copy, caller should copy himself.

func FilterKV ¶ added in v0.2.0

func FilterKV[K, V comparable](i iter.Seq2[K, V], keep func(K, V) bool) iter.Seq2[K, V]

func FromFile ¶ added in v0.3.2

func FromFile[T any](path string, parse func(io.Reader) iter.Seq[T]) iter.Seq[T]

func MergeKV ¶ added in v0.2.0

func MergeKV[K comparable, V any](is ...iter.Seq2[K, V]) iter.Seq2[K, V]

func MergeOrdered ¶

func MergeOrdered[T any](cmp func(T, T) bool, iters ...iter.Seq[T]) iter.Seq[T]
