How do I create a span from an array?
For example, you can create a Span from an array: From there, you can easily and efficiently create a span to represent/point to just a subset of this array, utilizing an overload of the span’s Slice method. From there you can index into the resulting span to write and read data in the relevant portion of the original array:
Why use span instead of an array?
From this brief description, two things should be clear: Span is defined in such a way that operations can be as efficient as on arrays: indexing into a span doesn’t require computation to determine the beginning from a pointer and its starting offset, as the ref field itself already encapsulates both.
