When an uncaught exception occurs during the mirrored execution of code, a MirroredUncaughtExceptionError is thrown.

This exception contains a mirror on the original exception object. It also contains an object which can be used to recover the stacktrace.

class MirroredUncaughtExceptionError extends MirroredError {
  MirroredUncaughtExceptionError(this.exception_mirror,
                                 this.exception_string,
                                 this.stacktrace) {}

  /** A mirror on the exception object. */
  final InstanceMirror exception_mirror;

  /** The result of toString() for the exception object. */
  final String exception_string;

  /** A stacktrace object for the uncaught exception. */
  final Object stacktrace;

  String toString() {
    return
        "Uncaught exception during mirrored execution: <${exception_string}>";
  }
}
