Hello, how to serialize data directly to my custom IO without using IOBuffer ?  
I just copy serialized data bytes from IOBuffer to custom IO object.

I have not tried this but I would expect that you would need to implement methods for the functions that `IOBuffer` supports for your custom IO. Functions like `take!` and `write`.

You can use reflection to find all the functions of `IOBuffer`:
