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, EnvConfigSource, TomlConfigSource,
};

// Load from TOML file with env override
let mut composite = CompositeConfigSource::new();
composite.add(TomlConfigSource::from_file("config.toml"));
composite.add(EnvConfigSource::with_prefix("APP_"));

let mut config = Config::new();
config.merge_from_source(&composite).unwrap();
