LogfileBackend

gatel_core::observability

Struct LogfileBackend 

Source 
pub struct LogfileBackend { /* private fields */ }
Expand description

A rotating log file writer.

Logs are appended to the current file. When the file exceeds rotate_size, it is renamed with a numeric suffix and a new file is opened. Up to rotate_keep old files are retained.

Implementations§

Source§

impl LogfileBackend

Source

pub fn new( path: impl Into<PathBuf>, rotate_size: u64, rotate_keep: usize, ) -> Result<Self>

Open or create a log file at path.

Source

pub fn write_line(&self, line: &str) -> Result<()>

Write a log line. Rotates if size threshold is exceeded.
