How to call this scala method in play?

I came across the below method here

 implicit def toLazyOr[T](cons: Constraint[T]) = new {
  def or(other: Constraint[T]) = Constraint { field: T =>
    cons(field) match {
      case Valid => other(field)
      case Invalid => Invalid
    }
  }
}

I defined toLazyOr method and then I am trying to use it in my code. But, I am not sure how do I use this. I tried: 

 val adminForm = Form(
mapping(
  "email" -> (email verifying toLazyOr(nonEmpty, minLength(4)) ) 
  )

And: 

val adminForm = Form(
    mapping(
      "email" -> (email verifying toLazyOr(nonEmpty or minLength(4)) ) 
      )

Both are not working and my scala knowledge for the moment is very basic. Please help.

Without knowing very much about play:

If the implicit conversion is in scope, the following should work:

val adminForm = Form(
  mapping(
    "email" -> (email verifying (nonEmpty or minLength(4)))
  ))

That's the thing about implicit conversions: You don't have to call them explicitly. See this answer for more information about where the compiler is looking for implicits.
