INI is an informal standard for configuration files for some platforms or software. INI files are simple text files with a basic structure composed of "sections" and "properties".

This is an INI file parser in Rust.

rust-ini = "0.19"

• Create a Ini configuration file.

extern crate ini;
use ini::Ini;

fn main() {
    let mut conf = Ini::new();
    conf.with_section(None::<String>)
        .set("encoding", "utf-8");
    conf.with_section(Some("User"))
        .set("given_name", "Tommy")
        .set("family_name", "Green")
        .set("unicode", "Raspberry树莓");
    conf.with_section(Some("Book"))
        .set("name", "Rust cool");
    conf.write_to_file("conf.ini").unwrap();
}

Then you will get conf.ini

encoding=utf-8

[User]
given_name=Tommy
family_name=Green
unicode=Raspberry\x6811\x8393

[Book]
name=Rust cool

• Read from file conf.ini

use ini::Ini;

fn main() {
    let conf = Ini::load_from_file("conf.ini").unwrap();

    let section = conf.section(Some("User")).unwrap();
    let tommy = section.get("given_name").unwrap();
    let green = section.get("family_name").unwrap();

    println!("{:?} {:?}", tommy, green);

    // iterating
    for (sec, prop) in &conf {
        println!("Section: {:?}", sec);
        for (key, value) in prop.iter() {
            println!("{:?}:{:?}", key, value);
        }
    }
}
