Crate loadconf 

This library makes it simple to load configuration files from disk.

Configuration can be loaded into any struct that implements serde::Deserialize and std::default::Default.

The library will load the first struct it finds in the following list, falling back to the default if no files are found.

1. ./{name}
2. ./{name}.toml
3. ./.{name}
4. ./.{name}.toml
5. ~/.{name}
6. ~/.{name}.toml
7. ~/.config/{name}
8. ~/.config/{name}.toml
9. ~/.config/{name}/config
10. ~/.config/{name}/config.toml
11. /etc/.config/{name}
12. /etc/.config/{name}.toml
13. /etc/.config/{name}/config
14. /etc/.config/{name}/config.toml

Example Usage

#[macro_use]
extern crate serde_derive;
extern crate loadconf;

/// Sample configuration
#[derive(Deserialize)]
struct Config {
    /// Sample variable
    var: String,
}

impl Default for Config {
    fn default() -> Config {
        Config { var: "Test configuration.".to_string() }
    }
}

fn main() {
    use loadconf::Load;

    // Just search for configuration files
    let config = Config::load("sample");

    // Optionally use file specified on command line.
    use std::env;
    let mut args = env::args();
    args.next();
    let config = Config::fallback_load("sample", args.next());
}
