+/// A contiguous container is a container that keeps all of its elements
+/// in a contiguous region of memory. The container owns the region of memory
+/// <c>[beg, end)</c>; the memory <c>[beg, mid)</c> is used to store the
+/// current elements, and the memory <c>[mid, end)</c> is reserved for future
+/// elements (<c>beg <= mid <= end</c>). For example, in
+/// <c>std::vector<> v</c>:
+///
+/// \code
+/// beg = &v[0];
+/// end = beg + v.capacity() * sizeof(v[0]);
+/// mid = beg + v.size() * sizeof(v[0]);
+/// \endcode
+///
+/// This annotation tells the Sanitizer tool about the current state of the
+/// container so that the tool can report errors when memory from
+/// <c>[mid, end)</c> is accessed. Insert this annotation into methods like
+/// <c>push_back()</c> or <c>pop_back()</c>. Supply the old and new values of
+/// <c>mid</c>(<c><i>old_mid</i></c> and <c><i>new_mid</i></c>). In the initial
+/// state <c>mid == end</c>, so that should be the final state when the
+/// container is destroyed or when the container reallocates the storage.
+///
+/// For ASan, <c><i>beg</i></c> should be 8-aligned and <c><i>end</i></c>
+/// should be either 8-aligned or it should point to the end of a separate
+/// heap-, stack-, or global-allocated buffer. So the following example will
+/// not work:
+///
+/// \code
+/// int64_t x[2]; // 16 bytes, 8-aligned
+/// char *beg = (char *)&x[0];
+/// char *end = beg + 12; // Not 8-aligned, not the end of the buffer
+/// \endcode
+///
+/// The following, however, will work:
+/// \code
+/// int32_t x[3]; // 12 bytes, but 8-aligned under ASan.
+/// char *beg = (char*)&x[0];
+/// char *end = beg + 12; // Not 8-aligned, but is the end of the buffer
+/// \endcode
+///
+/// \note Use this function with caution and do not use for anything other
+/// than vector-like classes.

+// `LocalAddressSpaceView` provides the local (i.e. target and current address
+// space are the same) implementation of the `AddressSpaveView` 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
+// instansiated 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.
