shep_core/lib.rs
1//! Shared foundation of the shep workspace
2//!
3//! Typed configuration (Flockfile + daemon config), value newtypes,
4//! process selectors, `$SHEP_HOME` paths, and wire protocol version 1.
5//! Every other crate depends on this one; it depends on no sibling.
6//!
7//! # Quick start
8//! ```
9//! use shep_core::prelude::*;
10//!
11//! let app: AppConfig = toml::from_str("name = \"web\"\nscript = \"./srv\"").unwrap();
12//! assert!(app.autorestart);
13//! let limit: MemSize = "512M".parse().unwrap();
14//! assert_eq!(limit.bytes(), 512 << 20);
15//! ```
16//!
17//! Module-by-module design: `docs/systematic-refactor/refactor-workspace/map.md`;
18//! behavior contract: `docs/specs/shep-v1.md`.
