### Instance Constructors

1.  new ImplicitComputation(iss: Analyzer.Infoss, isLocalToCallsite: Boolean)

   iss

     list of list of infos

   isLocalToCallsite

     if true, `iss` represents in-scope implicits, which must respect the normal rules of shadowing. The head of the list `iss` must represent implicits from the closest enclosing scope, and so on.

31.  lazy val wildPtNotInstantiable: Boolean

    Faster implicit search.

    Faster implicit search. Overall idea:

    - prune aggressively
    - find the most likely one
    - if it matches, forget about all others it improves upon
32.  object DivergentImplicitRecovery

    Preventing a divergent implicit from terminating implicit search, so that if there is a best candidate it can still be selected.

### Deprecated Value Members

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

     This member is added by an implicit conversion from ImplicitComputation toStringFormat[ImplicitComputation] 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): (ImplicitComputation, B)
   Implicit
     This member is added by an implicit conversion from ImplicitComputation toArrowAssoc[ImplicitComputation] 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.
