        # Modifies a subnet attribute.
        #
        # ==== Parameters
        # * SubnetId<~String> - The id of the subnet to modify
        # * options<~Hash>:
        #   * MapPublicIpOnLaunch<~Boolean> - Modifies the public IP addressing behavior for the subnet. 
        #     Specify true to indicate that instances launched into the specified subnet should be assigned a public IP address. 
        #     If set to true, the instance receives a public IP address only if the instance is launched with a single, 
        #     new network interface with the device index of 0.
        #
        # === Returns
        # * response<~Excon::Response>:
        # * body<~Hash>:
        # * 'requestId'<~String> - Id of request
        # * 'return'<~Boolean> - Returns true if the request succeeds. Otherwise, returns an error.
