velesdb-memory 0.8.0

//! Shared helpers for the `velesdb-memory` integration tests.
//!
//! Uses the deterministic, network-free `HashEmbedder` so every suite is fully
//! reproducible and air-gapped (mirrors the repo's `fake_embed` examples).
#![allow(dead_code)] // Each test binary uses a different subset of these helpers.
