StructTypeInfo represents the TypeInfo of a struct. A struct contains one or more fields each of which has a unique name and its own TypeInfo. Different fields can have the same or different TypeInfo. Always use the TypeInfoFactory to create new TypeInfo objects, instead of directly creating an instance of this class.
