trait Structural[Mixin] extends Serializable

A type class that converts a class type to a refinement type

This Structural type class provides an extension method structuralize via implicit view, which can be import as follow:

import com.thoughtworks.feature.Structural.ops._
Source
Structural.scala
Examples:

  1. Given a class that contains abstract types:

    trait Container extends Iterable[String] {
  trait InnerApi
  type Inner <: InnerApi
  def inner: Inner = ???
  type Self0 >: this.type
  def self: Self0 = this
}
val container: Container = new Container { def iterator = Iterator.empty }

    When converting it to a structural type

    import scala.language.higherKinds
val myStruct = container.structuralize

    Then methods on the converted struct should be able to access via reflective call

    import scala.language.reflectiveCalls
myStruct.self should be(myStruct)
    2. ,

  2. Given a String

    val myString: String = "foo"

    When converting it to a structural type

    val myStruct = myString.structuralize

    Then methods on the converted struct should be able to access via reflective call

    import scala.language.reflectiveCalls
myStruct.startsWith("f") should be(true)

    However, the struct is not a String

    "myStruct: String" shouldNot typeCheck
