(Since version 2.12.16) Use
formatString.format(value)instead ofvalue.formatted(formatString), or use thef""string interpolator. In Java 15 and later,formattedresolves to the new method in String which has reversed parameters.
- def →[B](y: B): (Recover[T], B)
- Implicit
- This member is added by an implicit conversion from Recover[T] toArrowAssoc[Recover[T]] performed by method ArrowAssoc in scala.Predef.This conversion will take place only if T is a subclass of Option[Nothing] (T <: Option[Nothing]).
