3.  trait AsyncTraverser extends Global.Traverser

   Descends into the regions of the tree that are subject to the translation to a state machine by `async`.

   Descends into the regions of the tree that are subject to the translation to a state machine by `async`. When a nested template, function, or by-name argument is encountered, the descent stops, and `nestedClass` etc are invoked.

    Efficiently decorate each subtree within `t` with the result of `t exists isAwait`, and return a function that can be used on derived trees to efficiently test the same condition.

    If the derived tree contains synthetic wrapper trees, these will be recursed into in search of a sub tree that was decorated with the cached answer.

### Deprecated Value Members

1.  def formatted(fmtstr: String): String
   Implicit
     This member is added by an implicit conversion from AsyncAnalysis toStringFormat[AsyncAnalysis] performed by method StringFormat in scala.Predef.
   Definition Classes
     StringFormat
   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.

2.  def →[B](y: B): (AsyncAnalysis, B)
   Implicit
     This member is added by an implicit conversion from AsyncAnalysis toArrowAssoc[AsyncAnalysis] performed by method ArrowAssoc in scala.Predef.
   Definition Classes
     ArrowAssoc
   Annotations
     @deprecated
   Deprecated

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
