question: Adding additional layers

[eureka-cpu]

Hello, I'm wondering if there's some way to add an additional layer, for instance tracing-journald. If not, it would be cool to have another version of the init4 function that could take a closure that accepts additional impl Layer types and applies it as part of the install_fmt macro in install_tracing. 🙂

Or perhaps just exporting the install_fmt macro would be enough so that I could build a function to apply the extra layer.

Ah, just saw this

This crate is intended to be used as a base for all binaries produced by the init4 project. It is not intended for outside consumption.

you're welcome to re-use the code if you think it's useful. I'd be happy to make the macro public, or provide some intermediate functions. The real problem that necessitates the macro is that the layers are typed, so the type varies based on what layers you actually configure, making it hard to create a useful generic API
