Module cache 

Entity cache for snapshot-on-subscribe functionality.

This module provides an EntityCache that maintains full projected entities in memory with LRU eviction. When a new client subscribes, they receive cached snapshots immediately rather than waiting for the next live mutation.

Structs

CacheStats

A point-in-time count of an EntityCache’s contents.

EntityCache

Entity cache that maintains full projected entities with LRU eviction.

EntityCacheConfig

Configuration for the entity cache

EntityLifetimeCheckpoint

The authoritative account lifetime known for one projected entity.

LifetimeOrdering

Independent ordering metadata attached to one projected cache write.

SnapshotBatchConfig

Enums

CacheWrite

What EntityCache::upsert_with_append did with a patch.

PatchOrigin

Whether a patch creates its entity, as far as its source says.

Functions

cmp_seq

Compare two _seq values numerically. _seq format is “{slot}:{offset}” where slot is not zero-padded. This handles digit-count boundaries correctly (e.g., 99999999 < 100000000).

Type Aliases

EntityLifetimes

(view, key, checkpoint) in most-recently-changed order.

EntityTombstones

Legacy (view, key, _seq) barriers, retained only to restore snapshots written before account positions had their own ordering domain.
