 // specializations for basic types (like int and std::string) and types in the
 // 'base' project can be found in ipc/ipc_message_utils.h.  This file contains
 // specializations for types that are used by the content code, and which need
 // manual serialization code.  This is usually because they're not structs with
 // public members, or because the same type is being used in multiple
