* Generic enum serializer.

|
|
* This is a generic serializer for any enum type used in IPDL.
|
|
* Programmers can define ParamTraits<E> for enum type E by deriving
|
|
* EnumSerializer<E, smallestLegal, highGuard>.
|
|
*
|
|
* The serializer would check value againts a range specified by
|
|
* smallestLegal and highGuard. Only values from smallestLegal to
|
|
* highGuard are valid, include smallestLegal but highGuard.
|
|
*
|
|
* For example, following is definition of serializer for enum type FOO.
|
|
* \code
|
|
* enum FOO { FOO_FIRST, FOO_SECOND, FOO_LAST, NUM_FOO };
|
|

* template <>

* \endcode
|

* FOO_FIRST, FOO_SECOND, and FOO_LAST are valid value.
