//! # Common logging and configuration utilities
//!
//! ## The global Tari configuration file
//!
//! A single configuration file (usually `~/.tari/config.toml` is used to manage settings for all Tari applications
//! and nodes running on a single system, whether it's a base node, validator node, or wallet.
//!
//! Setting of configuration parameters is applied using the following order of precedence:
//!
//! 1. Command-line argument
//! 2. Environment variable
//! 3. `config.toml` file value (see details: [configuration])
//! 4. Configuration default
//!
//! The utilities exposed in this crate are opinionated, but flexible. In general, all data is stored in a `.tari`
//! folder under your home folder.
//!
//! ## Custom application configuration
//!
//! Tari configuration file allows adding custom application specific sections. Tari is using [config] crate
//! to load configurations and gives access to [`config::Config`] struct so that apps might be flexible.
//! Though as tari apps follow certain configurability assumptions, tari_common provides helper traits
//! which automate those with minimal code.
//!
//! ## CLI helpers
//!
//! Bootstrapping tari configuration files might be customized via CLI or env settings. To help with building
//! tari-enabled CLI from scratch as easy as possible this crate exposes [ConfigBootstrap] struct which
//! implements [structopt::StructOpt] trait and can be easily reused in any CLI.
//!
//! ## Example - CLI which is loading and deserializing the global config file
//!
//! ```edition2018
//! # use tari_common::*;
//! # use tari_test_utils::random::string;
//! # use tempfile::tempdir;
//! # use structopt::StructOpt;
//! # use tari_common::configuration::bootstrap::ApplicationType;
//! let mut args = ConfigBootstrap::from_args();
//! # let temp_dir = tempdir().unwrap();
//! # args.base_path = temp_dir.path().to_path_buf();
//! # args.init = true;
//! args.init_dirs(ApplicationType::BaseNode);
//! let config = args.load_configuration().unwrap();
//! let global = GlobalConfig::convert_from(config).unwrap();
//! assert_eq!(global.network, Network::Rincewind);
//! assert_eq!(global.blocking_threads, 4);
//! # std::fs::remove_dir_all(temp_dir).unwrap();
//! ```
