Crate config_lib 

config-lib - Multi-Format Configuration Library

A high-performance configuration management library supporting multiple formats including CONF, NOML, TOML, and JSON with advanced features like format preservation, async operations, and schema validation.

Quick Start

use config_lib::Config;

// Parse any supported format automatically
let mut config = Config::from_string("port = 8080\nname = \"MyApp\"", None)?;

// Access values with type safety
let port: i64 = config
    .get("port")
    .ok_or_else(|| config_lib::Error::key_not_found("port"))?
    .as_integer()?;
let name: String = config
    .get("name")
    .ok_or_else(|| config_lib::Error::key_not_found("name"))?
    .as_string()?
    .to_owned();

// Modify and save (preserves format and comments)
config.set("port", 9000)?;

Supported Formats

• CONF - Built-in parser for standard .conf files (default)
• NOML - Advanced configuration with dynamic features (feature: noml)
• TOML - Standard TOML format with format preservation (feature: toml)
• JSON - JSON format with edit capabilities (feature: json)

Features

• High Performance - Zero-copy parsing where possible
• Format Preservation - Maintains comments, whitespace, and formatting
• Async Native - Full async/await support (feature: async)
• Schema Validation - Type safety and validation (feature: schema)
• Cross Platform - Linux, macOS, and Windows support
• Type Safety - Rich type system with automatic conversions
