SqlDelight question:
Possible to remove any of this boilerplate code?
I have a database table called “Countries”, for which SqlDelight generated a data class “Countries”.
I then have a serializable Repository data class “CountryData”, used by Ktor to serialize the Api response.
These two data classes have basically the same properties, and at the moment I need to write this code to match the two objects, which seems to be a lot of boilerplate code: I have to write the same property 3 times.
Is it possible to simplify in any way?

fun LocalDb.getCountriesList() : List<CountryData> {
    return countriesQueries.getCountriesList(
        mapper = { name, population, first_doses, fully_vaccinated ->
            CountryData(name = name, population = population, firstDoses = first_doses, fullyVaccinated = fully_vaccinated)
        }).executeAsList()
}

Just create a function that does this work for you and pass it in as a reference

I just got the answer there by JW.
Solution is pretty simple:

fun LocalDb.getCountriesList() : List<CountryData> {
    return countriesQueries.getCountriesList(mapper = ::CountryData).executeAsList()
}

That works too!
