1//! Shared per-plugin runtime — the `Engine` + `AST` adapters hold by
2//! reference.
3//!
4//! Each loaded Rhai plugin owns one [`RhaiPluginRuntime`]: a Send + Sync
5//! handle wrapping the configured `rhai::Engine` and the compiled `AST`.
6//! Adapters (`RhaiScalarFn`, `RhaiAggregateFn`, `RhaiProcedure`) hold
7//! `Arc<RhaiPluginRuntime>` clones so the underlying state isn't
8//! duplicated per registered function.
