FileStopper

gepa::utils::stop_condition

Struct FileStopper 

Source 
pub struct FileStopper {
    pub path: PathBuf,
}
Expand description

Stop the optimisation loop when a sentinel file appears on disk.

This is useful for graceful shutdown via an external process or script: touching the sentinel file causes the engine to stop at the next iteration boundary, after which the current state is serialised normally.

§Example

use gepa::utils::stop_condition::FileStopper;
let stopper = FileStopper::new("/tmp/stop_gepa");

Fields§

§path: PathBuf

Path of the sentinel file to watch.
