# withContiguousStorageIfAvailable(_:) Access contents of the buffer if available as contiguous memory block. ``` func withContiguousStorageIfAvailable(_ body: (UnsafeRawBufferPointer) throws -> sending R) rethrows -> sending R? ``` ## Discussion This method calls body(buffer), where buffer is a pointer to the block buffers contiguous storage. If the contiguous storage doesn’t exist, the method doesn’t call body — it immediately returns nil. --- Copyright © 2026 Apple Inc.
