Returns a span containing the final elements of the span, up to the given maximum length.
Declaration
func extracting(last maxLength: Int) -> Span<Element>Parameters
- maxLength:
The maximum number of elements to return.
maxLengthmust be greater than or equal to zero.
Return Value
A span with at most maxLength elements.
Discussion
If the maximum length exceeds the length of this span, the result contains all the elements.
The returned span’s first item is always at offset 0; unlike buffer slices, extracted spans do not share their indices with the span from which they are extracted.
