//
// `LocalAddressSpaceView` provides the local (i.e. target and current address
// space are the same) implementation of the `AddressSpaceView` interface which
// provides a simple interface to load memory from another process (i.e.
// out-of-process)
//
// The `AddressSpaceView` interface requires that the type can be used as a
// template parameter to objects that wish to be able to operate in an
// out-of-process manner. In normal usage, objects are in-process and are thus
// instantiated with the `LocalAddressSpaceView` type. This type is used to
// load any pointers in instance methods. This implementation is effectively
// a no-op. When an object is to be used in an out-of-process manner it is
// instantiated with the `RemoteAddressSpaceView` type.
//
// By making `AddressSpaceView` a template parameter of an object, it can
// change its implementation at compile time which has no run time overhead.
// This also allows unifying in-process and out-of-process code which avoids
// code duplication.
