[swift-users] Data(bytesNoCopy:count:deallocator)

I create an UsafeMutableRawPointer using the allocate method.

Later on I want to create a Data struct from this pointer using the bytesNoCopy initializer. Which deallocator should I pass?

It looks like this:

let retPointer = UnsafeMutableRawPointer.allocate(bytes: size, alignedTo: MemoryLayout<UInt8>.alignment)

let d = Data(bytesNoCopy: retPointer, count: size,deallocator:Deallocator.free)
