klieo-embed-common

Shared Embedder trait + DummyEmbedder for klieo memory backends.

Before W3.A17 the trait was duplicated byte-for-byte across klieo-memory-sqlite::embedder and klieo-memory-qdrant::embedder. A downstream embedder (Ollama, OpenAI, fastembed, etc.) needed two impl Embedder blocks. This crate is the single home; both memory crates re-export from here so their public APIs stay source-stable.

Features

• Default — Embedder trait + DummyEmbedder (zero vectors).
• test-utils — adds FakeEmbedder (deterministic per-text hashing) for downstream test harnesses.

Example

use klieo_embed_common::{DummyEmbedder, Embedder};

let e = DummyEmbedder;
let vecs = e.embed(&["hello".into()]).await?;
assert_eq!(vecs[0].len(), e.dimension());
