So I am making a UI program for my own use, and decided it needs proper multithread-friendly logging.

I can see hslogger vs. fast-logger (monad-logger seem to be implemented on top of fast-logger, its dependency footprint seems a bit large for my taste)

How are they different? And do you have any of these to recommend?
