### Deprecated Value Members

1.  def formatted(fmtstr: String): String

     This member is added by an implicit conversion from TreeInfo to StringFormat[TreeInfo] performed by method StringFormat in scala.Predef.
   Definition Classes

   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.
