func Empty ¶

func Empty[E any]() iter.Seq[E]

Empty creates an iter.Seq that yields nothing.

func Gen ¶

func Gen[N core.Integer](from N, to N) iter.Seq[N]

Gen creates an iter.Seq that yield number in range.

If `to` less-equal than `from`, yield nothing as Empty.

Example:

source.Gen(2,5) => seq: 2,3,4
source.Gen(2,1) => seq:

func Once ¶

func Once[E any](v E) iter.Seq[E]

Once creates an iter.Seq that yields an element exactly once.

func Repeat ¶

func Repeat[E any](v E) iter.Seq[E]

Repeat creates an iter.Seq that endlessly repeats a single element.

func RepeatTimes ¶

func RepeatTimes[E any, N core.Integer](v E, n N) iter.Seq[E]

RepeatTimes creates an iter.Seq that repeats a single element a given number of times.

func Variadic ¶

func Variadic[E any](elems ...E) iter.Seq[E]

Variadic creates an iter.Seq from variadic elements.
