A3S Memory

Pluggable memory storage for AI agents — MemoryStore trait, FileMemoryStore, InMemoryStore, and relevance scoring

A3S Memory

a3s-memory is a standalone Rust crate that provides the storage layer for agent memory. It has no knowledge of agents, sessions, or context injection — it owns exactly one thing: storing and retrieving MemoryItems.
