pub struct RotatingFileOutput { /* private fields */ }

Rotating file output that creates new files when size limit is reached.

Implementations

impl RotatingFileOutput

pub fn new<P: AsRef<Path>>( base_path: P, max_size: u64, max_files: u32, json_format: bool, ) -> Result<Self>

Creates a new rotating file output.

Files are rotated when they exceed max_size bytes. Old files are numbered (e.g., app.log.1, app.log.2) and the oldest is deleted when max_files is reached.

Arguments

• base_path - Base path for log files
• max_size - Maximum file size in bytes before rotation
• max_files - Maximum number of rotated files to keep
• json_format - If true, writes JSON; otherwise plain text
