From: Junjie Mao <[email protected]> For the matcher of macro, "expr" is used for expressions, while "ident" is used for variable/function names, and "ty" matches types.
In define_property macro, $field is a member name of type $state, so it should be defined as "ident", though offset_of! doesn't complain about this. $type is the type of $field, since it is not used in the macro, so that no type mismatch error is triggered either. Fix fragment-specifiers of $field and $type.
