### is_nothrow_require

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

    template<
        typename T,
        typename... Properties>
    struct is_nothrow_require :
      public integral_constant< bool, automatically_determined >

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