Expected behavior of types.NullDecimal

[achempak-polymer]

I have a nullable Decimal column in our db (for Postgres 14), and it looks like sqlboiler marshals this into a types.NullDecimal object. What is the expected behavior if the value in the db is null? I thought that it would result in something like

types.NullDecimal {nil}

But it looks like it actually just results in a nil pointer. Is this expected? The generated type is not *types.NullDecimal (it's not a pointer type). It's just types.NullDecimal.

I ran into this issue when trying to convert a NullDecimal to a Decimal. I hot-fixed the issue by handling the panic caused by a nil pointer dereference when nullDecimal ends up being nil.

func NullDecimalToDecimal(nullDecimal types.NullDecimal) (out types.Decimal) {
	defer func() {
		if r := recover(); r != nil {
			out = types.NewDecimal(decimal.New(0, 0))
		}
	}()

	if nullDecimal.Big == nil {
		return types.NewDecimal(decimal.New(0, 0))
	}
	return types.NewDecimal(nullDecimal.Big)
}
