Equal returns whether two time ranges are equal.

func (Range) Intersect 

func (r Range) Intersect(other Range) (Range, bool)

Intersect calculates the intersection of the receiver range against the provided argument range iff there is an overlap between the two. It also returns a bool indicating if there was a valid intersection.

func (Range) IsEmpty 

func (r Range) IsEmpty() bool

IsEmpty returns whether the time range is empty.

func (Range) IterateBackward added in v0.11.0 

func (r Range) IterateBackward(stepSize time.Duration, f func(t time.Time) (shouldContinue bool))
