5// This file is used to define IPC::ParamTraits<> specializations for a number
6// of types so that they can be serialized over IPC.  IPC::ParamTraits<>
7// specializations for basic types (like int and std::string) and types in the
8// 'base' project can be found in ipc/ipc_message_utils.h.  This file contains
9// specializations for types that are used by the content code, and which need
10// manual serialization code.  This is usually because they're not structs with
11// public members, or because the same type is being used in multiple
12// *_messages.h headers.
