39    //! the log rotator configuration. If a log rotator configuration is provided, the log rotator
40    //! will automatically rotate the logs when necessary based on the provided configuration.
41    //!
42    //! # Arguments
43    //!
44    //! * `config` - The log configuration. Can be either a `LogConfig::Path` variant that specifies
45    //!   the log path or a `LogConfig::Rotator` variant that specifies the log path and the log
46    //!   rotator configuration.

48    //! # Examples
49    //! ### Set the log path without a log rotator:
