canic_core/
lib.rs

1//! Core Canic library used inside canisters.
2//!
3//! Most users should depend on the `canic` facade crate, which re-exports this crate
4//! under `canic::core` and exposes the common entrypoint macros:
5//! - `canic::build!` / `canic::build_root!` (in `build.rs`) to validate/embed `canic.toml`
6//! - `canic::start!` / `canic::start_root!` (in `lib.rs`) to wire lifecycle hooks and export endpoints
7//!
8//! ## Layering
9//!
10//! Canic is organized to keep endpoint code thin and policies centralized:
11//! - `access/` contains guard/auth/rule helpers for boundary enforcement.
12//! - `workflow/` implements orchestration and lifecycle workflows.
13//! - `policy/` owns deterministic decision rules.
14//! - `ops/` provides mechanical, reusable side-effecting operations.
15//! - `model/` owns storage (stable memory) and in-process registries/caches.
16//! - macro entrypoints live in the `canic` facade crate.
17//!
18//! The default flow is: endpoints → workflow → policy → ops → model.
