1//! Schema evaluation engine.
2//!
3//! This module contains the Rust implementation behind [`JSONEval`]: parsing,
4//! dependency tracking, evaluation, layout resolution, validation, subforms, and
5//! schema caches. Crate root re-exports stable public types so callers usually do
6//! not need to import from submodules directly.
