⚙️ opzioni

A simple and fast configuration library for Rust.

Installation

Add the library to your project via cargo:

cargo add opzioni

Features

By default all features are enabled. This allows to work with JSON, TOML and YAML configs.

If you want to only use a subset run:

cargo add opzioni --no-default-features --features json

Replace json with the features you want to enable. The available features are

• json
• yaml
• toml

Usage

First create a struct implementing Serialize, Deserialize and Default

```rust use serde::{Serialize, Deserialize}

[derive(Serialize, Deserialize, Default)]

struct MyConfig { name: String, age: u8 } ```

Then just load the config file using opzioni:

rust let config = opzioni::Config::<MyConfig>::configure().load(std::path::Path::new("myconfig.yml")).unwrap();

opzioni exposes a RwLock which can be used to modify the config data:

rust let lock = config.get(); let data = lock.read().unwrap(); // or let mut data = lock.write().unwrap();

Once you are done working with the config you can save the changes to disk by calling save:

rust config.save().unwrap();
