Function Backward

iter.go:22–31

Backward returns an iterator that yields the elements of the bitmap in decreasing order. Starting with Go 1.23, users can use a for loop to iterate over it.

(b *Bitmap)

// decreasing order. Starting with Go 1.23, users can use a for loop to iterate
// over it.
func Backward(b *Bitmap) iter.Seq[uint32] {
	return func(yield func(uint32) bool) {
		it := b.ReverseIterator()
		for it.HasNext() {
			if !yield(it.Next()) {
				return
			}
		}
	}
}

// Unset creates an iterator that yields values in the range [min, max] that are NOT contained in the bitmap.
// The iterator becomes invalid if the bitmap is modified (e.g., with Add or Remove).
