3Idiomatic [inotify] wrapper for the [Rust programming language].

5```Rust
6extern crate inotify;
7
8
9use std::env;
10
11use inotify::{
12    EventMask,
13    WatchMask,
14    Inotify,
15};
16
17
18fn main() {
19    let mut inotify = Inotify::init()
20        .expect("Failed to initialize inotify");
21
22    let current_dir = env::current_dir()
23        .expect("Failed to determine current directory");
24
25    inotify
26        .watches()
27        .add(
28            current_dir,
29            WatchMask::MODIFY | WatchMask::CREATE | WatchMask::DELETE,
30        )
31        .expect("Failed to add inotify watch");
32
33    println!("Watching current directory for activity...");
34
35    let mut buffer = [0u8; 4096];
36    loop {
37        let events = inotify
38            .read_events_blocking(&mut buffer)
39            .expect("Failed to read inotify events");
40
41        for event in events {
42            if event.mask.contains(EventMask::CREATE) {
43                if event.mask.contains(EventMask::ISDIR) {
44                    println!("Directory created: {:?}", event.name);
45                } else {
46                    println!("File created: {:?}", event.name);
47                }
48            } else if event.mask.contains(EventMask::DELETE) {
49                if event.mask.contains(EventMask::ISDIR) {
50                    println!("Directory deleted: {:?}", event.name);
51                } else {
52                    println!("File deleted: {:?}", event.name);
53                }
54            } else if event.mask.contains(EventMask::MODIFY) {
55                if event.mask.contains(EventMask::ISDIR) {
56                    println!("Directory modified: {:?}", event.name);
57                } else {
58                    println!("File modified: {:?}", event.name);
59                }
60            }
61        }
62    }
63}

67## Usage
68
69Include it in your `Cargo.toml`:
70
71```toml
72[dependencies]
73inotify = "0.11"
74```
75
76Please refer to the [documentation] and the example above, for information on how to use it in your code.
77
78Please note that inotify-rs is a relatively low-level wrapper around the original inotify API. And, of course, it is Linux-specific, just like inotify itself. If you are looking for a higher-level and platform-independent file system notification library, please consider [notify].
79
80If you need to access inotify in a way that this wrapper doesn't support, consider using [inotify-sys] instead.
81
82
83## Documentation
84
85The most important piece of documentation for inotify-rs is the **[API reference]**, as it contains a thorough description of the complete API, as well as examples.
86
87Additional examples can be found in the **[examples directory]**.
88
89Please also make sure to read the **[inotify man page]**. Inotify use can be hard to get right, and this low-level wrapper won't protect you from all mistakes.
