VibeD - REST API and vibed.web.auth framework

[holo via Digitalmars-d-learn]

Hello

I'm trying to use auth framework with REST api ( 
http://vibed.org/api/vibe.web.auth/ ).

Is it possible to use it with registerRestInterface? According to 
description under: 
http://vibed.org/api/vibe.web.auth/requiresAuth it should be 
available on both Web and REST.

Here is my example code and compilation errors bellow:

import vibe.d;
import vibe.web.auth;
import vibe.http.session;
import vibe.web.rest : registerRestInterface;
import vibe.web.web : noRoute;
import std.algorithm, std.array;


struct AuthInfo {
	string userName;
     bool premium;
     bool admin;

	@safe:
	bool isAdmin() { return this.admin; }
	bool isPremiumUser() { return this.premium; }
}


interface IfOAuthAPI
{
     void postLogin(ValidUsername login, ValidPassword password);
//    bool postTokenValidation(string token, string userName);
}

@path("/api")
@requiresAuth
class OAuthAPI : IfOAuthAPI
{


   @noRoute
   AuthInfo authenticate(scope HTTPServerRequest req, scope 
HTTPServerResponse res) @safe
	{
		if (!req.session || !req.session.isKeySet("auth"))
			throw new HTTPStatusException(HTTPStatus.forbidden, "Not 
authorized to perform this action!");

		return req.session.get!AuthInfo("auth");
   }

   this(MongoCollection coll)
   {
     collection = coll;
   }

   private:
     MongoCollection collection;

   public:
     @noAuth
     string postLogin(ValidUsername login, ValidPassword password)
     {
       logInfo("Recived data for" ~ login ~ "and" ~ password);

       Bson query = Bson(["username" : Bson(login)]);
       auto result = collection.find(query);

       foreach (i, doc; result)
         logInfo("Item %d: %s", i, doc.toJson().toString());

       logInfo("Sending respond");
       return "OK";

     }
}

And im getting such errors:

ms-frontpage ~master: building configuration "application"...
