FatalErrorException : Class User contains 3 abstract methods

[Daniel B]

When I go to url /wardrobe/login/remind for forgot password after insering my email :

Symfony \ Component \ Debug \ Exception \ FatalErrorException
Class User contains 3 abstract methods and must therefore be declared abstract or implement the remaining methods (Illuminate\Auth\UserInterface::getRememberToken, Illuminate\Auth\UserInterface::setRememberToken, Illuminate\Auth\UserInterface::getRememberTokenName)

open: /space/www/wardrobe/app/models/User.php
     * @return string
     */
    public function getReminderEmail()
    {
        return $this->email;
    }

}
