Configuration Source Module

Provides various configuration source implementations for loading configuration from different sources such as files, environment variables, etc.

Supported Sources

• PropertiesConfigSource: Loads configuration from Java .properties format files
• TomlConfigSource: Loads configuration from TOML format files
• YamlConfigSource: Loads configuration from YAML format files
• EnvFileConfigSource: Loads configuration from .env format files
• EnvConfigSource: Loads configuration from system environment variables
• CompositeConfigSource: Merges configuration from multiple sources

Examples

use qubit_config::Config;
use qubit_config::source::{
    CompositeConfigSource, ConfigSource, TomlConfigSource,
};

// Load from TOML file
let mut composite = CompositeConfigSource::new();
let temp_dir = tempfile::tempdir().unwrap();
let path = temp_dir.path().join("config.toml");
std::fs::write(&path, "port = 8080\n").unwrap();
composite.add(TomlConfigSource::from_file(path));

let mut config = Config::new();
config.merge_from_source(&composite).unwrap();
assert_eq!(config.get::<i64>("port").unwrap(), 8080);
