# extracting(_:)

Constructs a new span over all the bytes of this span.

```
func extracting(_: UnboundedRange) -> RawSpan
```

## Return Value

A `RawSpan` over all the bytes of this span.

## Discussion

The returned span’s first byte is always at offset 0; unlike buffer
slices, extracted spans do not share their indices with the
span from which they are extracted.

> Complexity: O(1)
