Crate luci

Define and read configuration file.

A configuration file must not be: execute by owner; read, write or execute by other users; read, write or execute by other groups. That mean a configuration file may has the following modes: 400 or 600. Other than that, reading returns error::ErrorKind::Insecured.

struct Configuration {
   pub host: String,
   pub port: u16,
}

fn main() {
   let files = ["examples/foo.json", "~/.config/foo.json", "/etc/foo.json"];
   let (config, file) = match luci::read_jsonc::<Configuration, _>(files.iter()) {
       Ok(v) => v,
       Err(e) => {
           println!("Can not read configuration file.\n{}", e);
           process::exit(1);
       }
   };
   println!("Read configuration from {}", file.to_string_lossy());
   println!("> host={}", config.host);
   println!("> port={}", config.port);
}
