sim-nest 0.2.2

//! # sim-nest -- the SIM umbrella crate (imported as `sim`)
//!
//! Published on crates.io as **`sim-nest`** (the bare name `sim` is taken), while
//! its library import identifier is `sim`. Depend on `sim-nest` and write
//! `use sim::...`; `use sim_nest::...` does not resolve. The `#[sim::sim_lib]`
//! and `#[sim::sim_fn]` macros use the same stable import identifier.
//!
//! SIM is an expandable Rust runtime built around a small protocol kernel and
//! loadable libraries. Its data flow is:
//!
//! ```text
//! tokens -> checked forms -> objects -> checked calls -> objects -> encoded forms
//! ```
//!
//! Lisp is one codec, not the system identity. Syntax, codecs, classes,
//! functions, number domains, checkers, evaluators, wasm adapters, loaders, and
//! the standard language surface are libraries loaded above the kernel.
//!
//! ## Umbrella role
//!
//! This crate aggregates the constellation's implementation crates through an
//! optional-dependency feature map and re-exports stable aliases including
//! `sim::kernel`, `sim::shape`, `sim::codec`, and the `codec_*`, `lib_*`,
//! `table_*`, and `list_*` families. The opt-in `expr-tree` feature exposes the
//! canonical expression-tree crates without adding facade policy. Authoring
//! helpers (`functions`, `classes`, `macros`, `shapes`, and `runtime`) are
//! available with `shape`. The canonical feature map is in `Cargo.toml`.
//!
//! ## Kernel boundary
//!
//! The kernel owns identity and transport types, coordination types such as
//! `Cx`, `Registry`, `Lib`, `Linker`, and `ExportRecord`, capabilities, stores,
//! ledgers, control policy, object/callable/class/shape/factory/evaluation
//! contracts, match results, and ABI transport shapes. It does not own concrete
//! language or codec parsing, number domains, arithmetic, user-facing help and
//! browse behavior, guest behavior above ABI transport, or product policy.
//! Extensible metadata remains open `ExportRecord`-style data; concrete
//! behavior is installed through `Lib`, `Linker`, and `ExportRecord`.
//!
//! ## Load-bearing concepts
//!
//! - **`Shape`** is the shared engine for parsing, checking, binding, dispatch,
//!   macro syntax, codec grammar, lambda locals, and overload selection.
//! - **Codecs are first-class runtime objects**, split into decoders and
//!   position-aware encoders. General codecs round-trip every shared `Expr`;
//!   domain codecs fail closed outside the domain they accept.
//! - **`realize` and `EvalFabric`** provide location-transparent distributed
//!   evaluation. Evaluation strategy is an injectable `EvalPolicy`.
//! - **Capabilities make power explicit.** Read-construct is the narrow path
//!   behind Lisp `#(...)`; it is distinct from broad read-eval, which remains
//!   disabled by default for untrusted input.
//! - **Number domains, lists, and tables are pluggable libraries.**
//! - **Wasm is a first-class runtime target and portable plugin ABI.**
//!
//! ## Embedding
//!
//! `runtime::install_core_runtime` is the embedding entry point when `shape` is
//! enabled. Build a `Cx`, install the core runtime, then install codecs and
//! behavior libraries through their helpers or through `Lib` and `Linker`:
//!
//! ```ignore
//! use std::sync::Arc;
//! use sim::kernel::{Cx, DefaultFactory, EagerPolicy};
//! use sim::runtime::install_core_runtime;
//!
//! let mut cx = Cx::new(Arc::new(EagerPolicy), Arc::new(DefaultFactory));
//! install_core_runtime(&mut cx);
//! ```
//!
//! The installer loads the registry-backed core and enabled default number
//! domains; applications then add only the libraries their distribution needs.
