Class MemoryStore

Volatile in-memory store.

It is useful for storing temporal small chains, e.g., fixtures for unit tests of game logic.

MemoryStore and MemoryKeyValueStore-backed TrieStateStore can be instantiated from a URI with memory: scheme using LoadStore(Uri), e.g.:

  • memory:
  • memory://?secure=true (trie keys are hashed)
