✨ Features

🎯 Core Features

✅ Type-safe Configuration - Auto-generate configuration structs via derive macros
✅ Multi-format Support - TOML, YAML, JSON, INI configuration files
✅ Environment Variable Override - Support environment variable overrides
✅ Configuration Validation - Built-in validator integration with custom validation rules and parallel validation
✅ Schema Generation - Auto-generate JSON Schema from configuration structs (requires schema feature)

⚡ Advanced Features

🚀 File Watching & Hot Reload - Real-time configuration file monitoring (requires watch feature)
🔐 Configuration Encryption - Support AES-256 encrypted storage for sensitive config
🌐 Remote Configuration Support - Load config from etcd, Consul, HTTP and other remote sources (requires remote feature)

🚀 Quick Start

Installation

🦀 Rust

[dependencies]
confers = "0.1.1"

Basic Usage

🎬 5-Minute Quick Start

Step 1: Define Configuration Structure

use confers::Config;
use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize, Config)]
#[config(validate)]
#[config(env_prefix = "APP_", format_detection = "Auto")]
pub struct AppConfig {
    pub name: String,
    pub port: u16,
    pub debug: bool,
}

Step 2: Create Configuration File

# config.toml
name = "my-app"
port = 8080
debug = true

Step 3: Load Configuration

fn main() -> anyhow::Result<()> {
    let config = AppConfig::load()?;
    
    println!("Loaded: {:?}", config);
    Ok(())
}

Step 4: Environment Variable Override

# Automatically override from environment variables
export APP_PORT=9090

use confers::Config;
use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize, Config)]
#[config(validate)]
#[config(env_prefix = "APP_")]
pub struct AppConfig {
    pub name: String,
    pub port: u16,
    pub debug: bool,
}

fn main() -> anyhow::Result<()> {
    // 1. Create configuration file
    let config_content = r#"
name = "my-app"
port = 8080
debug = true
"#;
    std::fs::write("config.toml", config_content)?;

    // 2. Load configuration
    let config = AppConfig::load()?;

    // 3. Print configuration
    println!("Loaded configuration: {:#?}", config);

    // Automatic validation during configuration loading
    println!("✅ Configuration loaded successfully!");

    Ok(())
}

💡 Real-world Examples

📝 Example 1: Basic Operations

use confers::Config;
use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize, Config)]
#[config(validate)]
pub struct BasicConfig {
    pub name: String,
    pub port: u16,
}

fn basic_example() -> anyhow::Result<()> {
    let config = BasicConfig::load()?;
    println!("Name: {}, Port: {}", config.name, config.port);
    Ok(())
}

Name: my-app, Port: 8080
✅ Success!

🔥 Example 2: Advanced Usage

use confers::Config;
use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize, Config)]
#[config(validate)]
#[config(env_prefix = "MYAPP_")]
pub struct AdvancedConfig {
    #[config(description = "Server port")]
    pub port: u16,
    #[config(default = "localhost")]
    pub host: String,
}

fn advanced_example() -> anyhow::Result<()> {
    let config = AdvancedConfig::load()?;
    println!("Server: {}:{}", config.host, config.port);
    Ok(())
}

Server: localhost:8080
✅ Complete!
