func withUnsafeBytes<R>(_ body: (UnsafeRawBufferPointer) throws -> R) rethrows -> R
Calls the given closure with the contents of underlying storage.
- note: Calling `withUnsafeBytes` multiple times does not guarantee that
the same buffer pointer will be passed in every time.
- warning: The buffer argument to the body should not be stored or used
outside of the lifetime of the call to the closure.
Clients should prefer the `withBytes` function to this one, because
`withBytes` uses the non-escapable type `RawSpan` to ensure that the
buffer argument is not stored outside of the closure.
