/// A protocol describing a type that can be attached to a test report or
/// written to disk when a test is run and which contains another value that it
/// stands in for.
///
/// To attach an attachable value to a test, pass it to ``Attachment/record(_:named:sourceLocation:)``.
/// To further configure an attachable value before you attach it, use it to
/// initialize an instance of ``Attachment`` and set its properties before
/// passing it to ``Attachment/record(_:sourceLocation:)``. An attachable
/// value can only be attached to a test once.
///
/// A type can conform to this protocol if it represents another type that
/// cannot directly conform to ``Attachable``, such as a non-final class or a
/// type declared in a third-party module.
