Enable logging to rolling log files with Rust log library

Requires the 'logging' feature to be specified at compile time.

This is a helper utility for configuring the Rust log and log4rs libraries to redirect the log macros (info!(), warn!(), error!(), etc) to both stdout and a rotating log file on disk.

If you specify the Home directory with a log named ".fruit.log" and a backup count of 3, eventually you will end up with the files ~/.fruit.log, ~/.fruit.log.1, ~/.fruit.log.2, and ~/.fruit.log.3

The maximum disk space used by the log files, in megabytes, will be:

(backup_count + 1) * max_size_mb

Arguments

filename - Filename for the log file, without path

dir - Directory to save log files in. This is provided as an enum, LogDir, which offers some standard logging directories, or allows specification of any custom directory.

max_size_mb - Max size (in megabytes) of the log file before it is rolled into an archive file in the same directory.

backup_count - Number of archived log files to keep before deleting old logs.

Returns

Full path to opened log file on disk
