* Update mod.rs
The following code uses a separator that is not compatible with Windows:
format!("{}/{}", file_config.path.clone(), rustfs_config::DEFAULT_SINK_FILE_LOG_FILE)
Change it to the following code:
std::path::Path::new(&file_config.path)
.join(rustfs_config::DEFAULT_SINK_FILE_LOG_FILE)
.to_string_lossy()
.to_string()
* Replaced format! macro with PathBuf::join to fix path separator issue on Windows.Tested on Windows 10 with Rust 1.85.0, paths now correctly use \ separator.
