5daemonize is a library for writing system daemons. Inspired by the Python library [thesharp/daemonize](https://github.com/thesharp/daemonize).

7Usage example:
8
9```rust
10extern crate daemonize;
11
12use std::fs::File;
13
14use daemonize::Daemonize;
15
16fn main() {
17 let stdout = File::create("/tmp/daemon.out").unwrap();
18 let stderr = File::create("/tmp/daemon.err").unwrap();
19
20 let daemonize = Daemonize::new()
21 .pid_file("/tmp/test.pid") // Every method except `new` and `start`
22 .chown_pid_file(true) // is optional, see `Daemonize` documentation
23 .working_directory("/tmp") // for default behaviour.
24 .user("nobody")
25 .group("daemon") // Group name
26 .group(2) // or group id.
27 .umask(0o777) // Set umask, `0o027` by default.
28 .stdout(stdout) // Redirect stdout to `/tmp/daemon.out`.
29 .stderr(stderr) // Redirect stderr to `/tmp/daemon.err`.
30 .privileged_action(|| "Executed before drop privileges");
31
32 match daemonize.start() {
33 Ok(_) => println!("Success, daemonized"),
34 Err(e) => eprintln!("Error, {}", e),
35 }
36}
