def mkClassFieldsFromSeqIsoImpl[A : Type](implicit evidence$1: Type[A], Quotes): Expr[(A => Seq[Long], (Seq[Long]) => A)]
Generates a pair of functions to convert a class to a sequence of longs and vice versa. The generated code is equivalent to the following:
Generates a pair of functions to convert a class to a sequence of longs and vice versa. The generated code is equivalent to the following:

val params = new A()
params.field1 = if idx < seq.size then seq(0) else 0L
