Functions

func ManmadePage

func ManmadePage(pager Pager, page Page) (Pager, Page)

ManmadePage 手动分页，这里用泛型写更好，我是1.16的，就不用泛型改interface类型了

func manmadePage[T any](items []T, page Page) ([]T, Page) {
	if len(items) == 0 {
		return nil, page.Clone(0)
	}
	pg := page.Clone(len(items))
	start, end := pg.GetStartAndEnd()
	items = items[start:end]
	return items, pg
}
