public struct Take: Fn
Take returns a new Collection or Page that contains num elements from the
head of the Collection or Page coll. If
take value is zero or negative, the
resulting collection is empty. When applied to a page, the returned page’s
after cursor is adjusted to only cover the taken elements.
As special cases:
takevalue is negative, after will be set to the same value as the original page’s before.
- If all elements from the original page were taken, after does not change.
