A Rust library for storing application properties on disk for persistence.
Write key-value pairs to the config and write it to disk... ```rust let mut config = Config::new("system-config-example").unwrap();
config.insert("key1", "value1"); config.insert("key2", "value2");
config.write().unwrap(); ```
Then retrieve the information at any other time, even after the application is restarted. ```rust let config = Config::new("system-config-example").unwrap();
let key1 = config.get("key1").unwrap(); let key2 = config.get("key2").unwrap();
println!("key1: {}", key1); println!("key2: {}", key2); ```
To demonstrate this I've created a few examples that do this exact thing.
$ cargo run -q --example write
$ cargo run -q --example read
key1: value1
key2: value2
$ cargo run -q --example clear
$ cargo run -q --example read
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', examples/read.rs:6:35
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Internally, system-config is basically an abstraction over HashMap, which reads and writes its information to disk in yaml format on each .read() and .write().
The file is written to a .yaml file inside of your config directory, as found by the dirs crate.
