my first scala fizzbuzz solution

FizzBuzz.scala

package katas

object FizzBuzz {

  def fizzBuzz(input:Int):String = {
    class Solution(val result:String, val filter:Int) {
      def isSatisfied(input:Int) = {
        input % filter == 0 || input.toString.contains(filter.toString)
      }
    }
    val solutions = List(new Solution("fizz",3),new Solution("buzz",5))
    val matchingSolutions: List[Solution] = solutions.filter(solution => solution.isSatisfied(input))
    matchingSolutions match {
      case Nil => input.toString
      case list:List[Solution] => list.map(_.result).mkString("")
    }
  }
}
