Function cleanup_run_logs 

Source 
fn cleanup_run_logs(log_dir: &Path, max_files: usize) -> Result<(), Error>
Expand description

Removes old log files to maintain the configured retention limit.

This function scans the log directory for files matching the pattern cadmus-*.json and deletes the oldest files if the count exceeds max_files.

Note: this relies on the run ID being a UUID v7 (time-ordered). Filenames are cadmus-<run_id>.json where <run_id> is generated with Uuid::now_v7(), so lexicographic sorting of the filenames corresponds to chronological order. Sorting by file name therefore yields oldest-first ordering for removal.

§Arguments

  • log_dir - Path to the directory containing log files
  • max_files - Maximum number of log files to retain (0 = keep all)

§Returns

Returns Ok(()) on success.

§Errors

Returns an error if:

  • The log directory cannot be read
  • Individual directory entries cannot be read
  • Old log files cannot be deleted
