Getter function to return a nested struct that contains mapping?

For example,

    struct SomeStruct {
        uint _someUint;
        uint _someUint2;
        mapping(address => uint) _someMapping;

A getter function for a non-nested struct could be

    function retSomeStruct() public returns(SomeStruct memory) {

But this doesn't work for the nested one,

TypeError: Types containing (nested) mappings can only be parameters or return variables of internal or library functions.

To return a struct containing _someUint and _someUint2, apart from destructing, is there other ways to just skip the mapping?
