io_handler

using fl::asio::io_handler

Initial value:

 
    fl::function<void(const error_code &ec, size_t bytes_transferred)>

Asio-style I/O completion handler signature.

Matches the standard async I/O handler: void(error_code, size_t). Maps to boost::asio's ReadHandler / WriteHandler concepts.
