Intermact API Reference / @intermact/core / RuntimeStateStore

Class: RuntimeStateStore

Defined in: packages/core/src/runtime/store.ts:19

Immutable runtime-state store keyed by object id. Each applyPatch produces a new state value for the target while leaving others referentially stable, so renderers can diff cheaply by identity (design.md §4.3, §15.2).

The store holds the RuntimeState union (2D | 3D) and dispatches the correct patch application by the stored state's dimension discriminator.
