    Args &&... args
)

Get a Response from loaned shared memory and construct the data with the given arguments.

Parameters:

• request The request to which the Response belongs to, to determine where to send the response
• args Arguments used to construct the data.

Return: An instance of the Response that resides in shared memory or an error if unable to allocate memory to loan.

The loaned Response is automatically released when it goes out of scope.

function send

cxx::expected< ServerSendError > send(
    Response< Res > && response
) override
