This rule reports functions inside data classes which have not been marked as a conversion function. Data classes should mainly be used to store data. This rule assumes that they should not contain any extra functions aside functions that help with converting objects from/to one another. Data classes will automatically have a generated equals, toString and hashCode function by the compiler.

Noncompliant Code
