dkdc-config

Configuration management for dkdc (don't know, don't care).

Overview

This crate provides centralized configuration management for all dkdc components. It handles:

• Path management for dkdc directories
• Configuration constants
• Platform-specific path handling

Usage

use dkdc_config::Config;

// Create config with default paths ($HOME/.dkdc)
let config = Config::new()?;

// Get various paths
let lake_dir = config.lake_dir();           // ~/.dkdc/dkdclake
let metadata = config.metadata_path();      // ~/.dkdc/dkdclake/metadata.db
let data = config.data_path();              // ~/.dkdc/dkdclake/data
let python = config.python_path();          // ~/.dkdc/venv/bin/python

// Ensure directories exist
config.ensure_directories()?;
config.ensure_metadata_db()?;
