mod.rs

//! Configuration for ma-core-based daemons.
//!
//! Provides [`Config`], a configuration model that supports:
//!
//! - native daemon bootstrapping from CLI/env/YAML/defaults via
//!   [`Config::from_args`]
//! - storage-agnostic serialization workflows (including wasm) via
//!   [`Config::from_yaml_str`] and [`Config::to_yaml_string`]
//!
//! Native `from_args` resolves fields from (in decreasing priority):
//!
//! 1. Explicit CLI arguments (via [`MaArgs`])
//! 2. `MA_<MA_DEFAULT_SLUG>_*` environment variables (slug-prefixed, set per binary)
//! 3. `MA_*` environment variables (static fallback, shared across binaries)
//! 4. YAML config file (`XDG_CONFIG_HOME/ma/<slug>.yaml`)
//! 5. Built-in defaults
//!
//! # Native compile-time constant requirement
//!
//! Binaries using [`Config::from_args`] **must** declare a compile-time
//! constant:
//!
//! ```no_run
//! const MA_DEFAULT_SLUG: &str = "panteia";
//! ```
//!
//! This constant serves a dual purpose:
//! - **Default slug** — used for file naming when `--slug` is not set.
//! - **Env-var prefix** — uppercased to `MA_PANTEIA_*` for env-var lookup.
//!   This prefix is fixed at compile time and cannot be changed at runtime.
//!   Only file-naming can be overridden via `--slug`.
