Custom log support via callback

[jakobhu]

Is there a way to capture log information from the internal Clarabel solver?
It seems that the rust backend is reporting via std::io::Result<()> - not sure how to capture that from C++.

That is - I would like to acquire the iteration information (pres, dres, etc.) - with the intention of displaying it myself. A callback with a string is how many third-party packages support that.

I've tried to tie with 'stdout' - but that is not very robust, and especially problematic on Windows.
