How to use tokio-modbus with dynamic values ? about tokio-modbus

[uklotzde]

That's obvious. get_datas() is invoked once on server startup and stored. Each response is populated with a copy of that immutable data.

Thanks @uklotzde to point the lack of my skills on rust development, no offense. 😄
In reality, I've shown you the least advanced code, but working, to let it as simple as possible, but I already tried to make callback function to be called by call function and be able to generate response without success.
But as I said, I don't have the skills, and I don't know how to make the response dynamic the right way.
What can I do, implement callback seems to be a good solution, but is it the right way ?

This is not a tokio-modbus issue, but a general programming question.

If I would provide you the correct solution you would probably hit the next road block soon. The solution might also depend on your requirements and goals that I am not aware of.

Yes @uklotzde you've right, I will try to find the solution on my own.
