reprs:

  • VoidPointer
  • TypedPointer, stores target type in REPR
  • CheckedPointer, stores target type in REPR and bounds in body

types:

  • OpaquePointer backed by VoidPointer
  • TransparentPointer backed by TypedPointer, pass-through method calls
  • MovablePointer backed by CheckedPointer, allows pointer arithmetics and explicit deref()
  • UnsafePointer backed by VoidPointer, allows byte-wise pointer arithmetics and explicit cast() to other pointer types
