Module config_loader 

Configuration loader for the TxGate signing service.

This module provides utilities for loading, saving, and managing configuration files from the filesystem. It handles path expansion (e.g., ~ to home directory) and provides sensible defaults when configuration files don’t exist.

Default Location

Configuration is stored at ~/.txgate/config.toml by default.

Examples

Loading configuration with defaults

use txgate_core::config_loader::load_config;

// Load config from default location, using defaults if file doesn't exist
let config = load_config().expect("failed to load config");

Using ConfigLoader for more control

use txgate_core::config_loader::ConfigLoader;
use std::path::PathBuf;

// Create loader with default base directory (~/.txgate)
let loader = ConfigLoader::new().expect("failed to create loader");

// Check if config exists
if loader.exists() {
    let config = loader.load().expect("failed to load config");
    println!("Loaded config with timeout: {}s", config.server.timeout_secs);
} else {
    // Write default configuration
    loader.write_default().expect("failed to write default config");
}

Custom base directory

use txgate_core::config_loader::ConfigLoader;
use std::path::PathBuf;

let loader = ConfigLoader::with_base_dir(PathBuf::from("/custom/txgate"));
let config = loader.load().expect("failed to load config");
