Tuple4FromExpr

given Tuple4FromExpr[T1, T2, T3, T4](using val x$1: Type[T1], val x$2: Type[T2], val x$3: Type[T3], val x$4: Type[T4], val x$5: FromExpr[T1], val x$6: FromExpr[T2], val x$7: FromExpr[T3], val x$8: FromExpr[T4]): FromExpr[(T1, T2, T3, T4)]

Default implementation of FromExpr[Tuple4[...]]

  • Transform '{Tuple4(x1, ..., x4)} into Some(Tuple4(x1, ..., x4)) if all xi can be transformed using FromExpr[Ti]
  • Otherwise returns None
