Configuration file directly in the crate

[fdubois1]

It would be nice if we could init log4rs with a file in the crate.

It exists "std::include_str!" to get the content of a file then log4rs could read it. I know that it is possible to configure it by code by building the config ourself, but would be useful to just add a yaml file to my crate and init log4rs with it.

Does it make sense ?
Thanks

You can deserialize the string into a RawConfig and then build the logger out of that: https://docs.rs/log4rs/0.8.0/log4rs/file/struct.RawConfig.html

But to be honest, I don't see how to build the RawConfig. I saw in init_file that rawConfig is built like this : let config = format.parse(&source)?;

But Format type is private. I don't see how I can build that RawConfig object. Sorry if it is a dumb question and thanks for your help.

RawConfig implements Deserialize (it unfortunately doesn't show up in rustdoc), so you'd just do serde_yaml::from_string::<RawConfig>(my_config).

Ah, awesome, thanks a lot for your help !!!
