How to use tracing in across dylibs

I have a solution for log facade, with tracing-log, but what if I want to use full functionality of tracing? This approach will work if I figure out how to forward full functionality of tracing(mainly macros that involves global variables)

I'm assuming that the usage of tracing across dylibs implies exposing tracing-specific functionality through a C FFI. In that case, I suggest looking at #948 for some prior discussion on the subject.

A crate for this purpose is available. No unsafe is used at all. Also support logs
