extracting(_:)

Constructs a new span over the bytes within the supplied range of positions within this span.

Declaration

mutating func extracting(_ bounds: Range<Int>) -> MutableRawSpan

Parameters

bounds:
A valid range of positions. Every position in this range must be within the bounds of this MutableRawSpan.

Return Value

A MutableRawSpan over the bytes within bounds.

Discussion

The returned span represents a mutation of this span.

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.
