Rust Daemon Template

This is a template for writing a daemon using Rust. The template includes

• Command-line argument parsing
• Config loading from hard-coded location using yaml
• A run() function called by main() to support ? operator. Errors returned from run() are simply printed to stderr using the Display impl, and the process exits with 1.
• Logging to stderr using the log crate and controlled by the command line -v flags.
• Signal handling

To get started, clone this project and s/rust_daemon_template/foo/.

The template can run out of the box using

cargo run -- --config ./config.yml.example

To add application logic, edit the App type and its Application impl in app.rs, the command-line options in cli.rs, and the config file format in config.rs.

FAQ

• Where is the daemonization logic? There isn't any; your system's process manager should be able to handle this for you.
