Interface LaravelUi5\Core\Contracts\CacheSerializable

Contract for objects that round-trip the registry cache.

The registry cache serialises to a plain PHP array file. An object placed in that array would otherwise be flattened to its class name by the cache writer's get_class() fallback — a silent, lossy degradation: a wrong value wearing the right shape, found only at runtime under cache (the F11 class of bug, surfaced by SlotCatalogEntry, the first non-Module/Artifact DTO put through the cache).

A cacheable DTO implements this contract so the cache writer serialises it structurally via {@see toCache()} and the reader rebuilds it via {@see fromCache()} — instead of relying on a hardcoded type whitelist, and instead of each consumer hand-rolling the (de)serialisation per DTO.

Implementations MUST be lossless — fromCache($x->toCache()) reconstructs an equivalent object — and {@see toCache()} MUST return only cache-safe values (scalars and nested arrays of scalars; no objects, closures, or resources).
