Copy into the specified dst starting at the specified dstOffset the specified length bytes starting at the specified srcOffset in the specified src. The behavior is undefined unless 0 <= dstOffset, 0 <= srcOffset, 0 <= length, dst || 0 == length, !dst || dstOffset <= dst‐>length() ‐ length, and srcOffset <= src‐>length() ‐ length. Note that this operation does not require dst to have a blob buffer factory in that it does not create or destroy blobs ‐‐ it simply copies data from src into dst, so dst must already have room for length bytes of data added at dstOffset.
