Notify

Crates.ioCrates.ioCrates.ioTravisCode of Conduct

Cross-platform filesystem notification library for Rust.

Install

[dependencies]
notify = "^2.3"

Usage

extern crate notify;

use notify::{RecommendedWatcher, Error, Watcher};
use std::sync::mpsc::channel;

fn main() {
  // Create a channel to receive the events.
  let (tx, rx) = channel();

  // Automatically select the best implementation for your platform.
  // You can also access each implementation directly e.g. INotifyWatcher.
  let mut w: Result<RecommendedWatcher, Error> = Watcher::new(tx);

  match w {
    Ok(mut watcher) => {
      // Add a path to be watched. All files and directories at that path and
      // below will be monitored for changes.
      watcher.watch("/home/test/notify");

      // You'll probably want to do that in a loop. The type to match for is
      // notify::Event, look at src/lib.rs for details.
      match rx.recv() {
        _ => println!("Recv.")
      }
    },
    Err(e) => println!("Error")
  }
}

Origins

Inspired by Go's fsnotify, born out of need for cargo watch, and general frustration at the non-existence of C/Rust cross-platform notify libraries.
