Rationale for this change
( #50251 ) Enhancement for ArrayData
What changes are included in this PR?
Added GetSpan(int i, int64_t length) for read-only typed access to ArrayData.
Added GetMutableSpan(int i, int64_t length) for writable typed access to ArrayData.
Are these changes tested?
New unit tests were added in array_test.cc:
GetSpanRespectsOffset
GetMutableSpanRespectsOffset
The tests verify:
correct slicing with offset
correct span length
correctness of data read through spans
correctness of in-place mutation through GetMutableSpan
