### is_nothrow_query

A type trait that determines whether a `query` expression will not throw.

    template<
        typename T,
        typename Property>
    struct is_nothrow_query :
      public integral_constant< bool, automatically_determined >

Class template `is_nothrow_query` is a trait that is derived from `true_type` if the expression `asio::query(std::declval<T>(), std::declval<Property>())` is `noexcept`; otherwise `false_type`.
