orion-conf

Lightweight, feature‑gated config IO for Rust. Enable only the formats you need.

Quick Start

use orion_conf::{ConfigIO, YamlIO};
use serde::{Deserialize, Serialize};

#[derive(Deserialize, Serialize, Debug, PartialEq)]
struct AppCfg { name: String, value: i32 }

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // cargo run --features yaml
    let cfg = AppCfg { name: "demo".into(), value: 7 };
    let path = std::path::Path::new("app.yaml");

    cfg.save_conf(path)?;                 // delegates by feature priority (YAML > TOML > JSON > INI)
    let loaded = AppCfg::load_conf(path)?; // same priority for loading

    // Or call the format explicitly
    cfg.save_yaml(path)?;
    let _ = AppCfg::load_yaml(path)?;
    Ok(())
}

Features

• Formats (opt‑in): yaml, toml, json, ini
• Combined: formats (all), full (all)
• Default features: empty

Key Traits (0.3+)

• ConfigIO: unified read/write with feature‑based priority
• YamlIO/TomlIO/JsonIO/IniIO: explicit format IO

Examples

• JSON only: cargo run --example json_feature_test --features json
• YAML+JSON priority: cargo run --example feature_priority_test --features yaml,json
