sim-lib-view 0.1.0

//! View/editor codec contracts, Shape-based lens dispatch, lens stack, and the
//! universal default lens for the SIM Web-UI (WEBUI_4).
//!
//! A view is a codec object in the encode direction (`Value -> Scene`); an
//! editor is a codec object in the decode direction
//! (`(Value, Intent) -> Draft`, then `Draft -> operation`). A lens pairs a view
//! with an optional editor. View selection is overload selection, so the
//! dispatcher reuses the kernel `Shape` matcher rather than inventing a second
//! selection ladder.
//!
//! This crate provides the lens [`contract`] (open metadata plus the view and
//! editor traits), the Shape-based [`dispatch`] machinery, the universal
//! default lens, the lens [`stack`], and experience [`mode`]s.
//!
//! # Example
//!
//! Any value opens in the universal default lens, rendered at the active mode's
//! depth (Household, Builder, Systems):
//!
//! ```
//! use sim_kernel::Expr;
//! use sim_lib_view::{Mode, universal_scene};
//!
//! let scene = universal_scene(&Expr::Nil, Mode::Builder);
//! assert!(sim_lib_scene::validate_scene(&scene).is_ok());
//! ```
