It should serialize a struct
TestStruct value = TestStruct(1, "2"); const TestStruct cvalue = TestStruct(1, "2"); immutable TestStruct ivalue = TestStruct(1, "2"); SerializerRegistry.instance.serialize(value).should.equal(`TestStruct(1, "2")`); SerializerRegistry.instance.serialize(cvalue).should.equal(`TestStruct(1, "2")`); SerializerRegistry.instance.serialize(ivalue).should.equal(`TestStruct(1, "2")`);
