log4rs?

Afaiu tracing is where the ecosystem moves too, it is also used by tokio & and at least some parts of core, and it is async aware/can be used better in async situations as it has utilities for that.

I just recently learned about tracing myself, so I am not sure if there is a complete implementation as log4rs for log yet. The afro mentioned link has a section about the ecosystem.
tracing_subscriber provides a simple implementation, and there appears to be tracing-appender for simple file-outputting.

There are also compatible crates to be able to output log statements via tracing.
