Struct FileWatcher 

pub struct FileWatcher { /* private fields */ }

Watches a file for changes and unblocks the provided blocker when a change occurs.

use std::env::current_dir;
use ed_journals::fs::{auto_detect_journal_path, FileWatcher, SyncBlocker};

let path = current_dir()
    .unwrap()
    .join("..")
    .join("test-files")
    .join("journals")
    .join("Journal.2000-01-01T100000.01.log");

let blocker = SyncBlocker::new();
let file_watcher = FileWatcher::new(&path, &blocker).unwrap();

blocker.wait().unwrap();
// Something changed

Keep in mind that this watcher needs to be kept in scope for as long as you want to receive notifications.
