  This trait finds implicit conversions for a class in the default scope and creates scaladoc entries for each of them.

  This trait finds implicit conversions for a class in the default scope and creates scaladoc entries for each of them.

  Let's take this as an example:

      object Test {
        class A

        class B {
          def foo = 1
        }

        class C extends B {
          def bar = 2
          class D
        }

        implicit def conv(a: A) = new C
      }

  Overview: - scaladoc-ing the above classes, `A` will get two more methods: foo and bar, over its default methods - the nested classes (specifically `D` above), abstract types, type aliases and constructor members are not added to `A` (see makeMember0 in ModelFactory, last 3 cases) - the members added by implicit conversion are always listed under the implicit conversion, not under the class they actually come from (`foo` will be listed as coming from the implicit conversion to `C` instead of `B`) - see `definitionName` in MemberImpl

# ImplicitNotFound

###

#### class ImplicitNotFound extends Exception

This is a flag that indicates whether to eliminate implicits that cannot be satisfied within the current scope. For example, if an implicit conversion requires that there is a Numeric[T] in scope:

    class A[T]
    class B extends A[Int]
    class C extends A[String]
    implicit def enrichA[T: Numeric](a: A[T]): D

For B, no constraints are generated as Numeric[Int] is already in the default scope. On the other hand, for the conversion from C to D, depending on -implicits-show-all, the conversion can:

- not be generated at all, since there's no Numeric[String] in scope (if ran without -implicits-show-all)
- generated with a *weird* constraint, Numeric[String] as the user might add it by hand (if flag is enabled)

### Deprecated Value Members

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

     This member is added by an implicit conversion from (ModelFactoryImplicitSupport.this)#ImplicitNotFound toStringFormat[(ModelFactoryImplicitSupport.this)#ImplicitNotFound] 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): ((ModelFactoryImplicitSupport.this)#ImplicitNotFound, B)

     This member is added by an implicit conversion from (ModelFactoryImplicitSupport.this)#ImplicitNotFound toArrowAssoc[(ModelFactoryImplicitSupport.this)#ImplicitNotFound] 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.
