Alex Crichton 2be457c295 Change the return type of `SharedMemory::data` (#5240 ) This commit is an attempt at improving the safety of using the return value of the `SharedMemory::data` method. Previously this returned `mut [u8]` which, while correct, is unwieldy and unsafe to work with. The new return value of `&[UnsafeCell<u8>]` has a few advantages: The lifetime of the returned data is now connected to the `SharedMemory` itself, removing the possibility for a class of errors of accidentally using the prior `mut [u8]` beyond its original lifetime. It's not possibly to safely access `.len()` as opposed to requiring an `unsafe` dereference before. * The data internally within the slice is now what retains the `unsafe` bits, namely indicating that accessing any memory inside of the contents returned is `unsafe` but addressing it is safe. I was inspired by the `wiggle`-based discussion on #5229 and felt it appropriate to apply a similar change here.		2 years ago
