/// serialized, but this behavior can be changed by specializing this

/// sense for different types; a class need only implement one of them.

/// by the Serializer and Deserializer using the EmitOwnedPtr, etc. methods.

/// To serialize the actual object referred to by a pointer, the class

/// of the object either must implement the methods called by the default
|
|
/// behavior of SerializeTrait, or specialize SerializeTrait. This latter

/// is useful when one cannot add methods to an existing class (for example).
