// This file contains ParamTraits templates to support serialization of WebKit
// data types over IPC.
//
// NOTE: IT IS IMPORTANT THAT ONLY POD (plain old data) TYPES ARE SERIALIZED.
//
// There are several reasons for this restrictions:
//
//   o  We don't want inclusion of this file to imply linking to WebKit code.
//
//   o  Many WebKit structures are not thread-safe.  WebString, for example,
//      contains a reference counted buffer, which does not use thread-safe
//      reference counting.  If we allowed serializing WebString, then we may
//      run the risk of introducing subtle thread-safety bugs if people passed a
//      WebString across threads via PostTask(NewRunnableMethod(...)).
//
//   o  The WebKit API has redundant types for strings, and we should avoid
//      using those beyond code that interfaces with the WebKit API.
