Module embedder 

Embedding abstraction for the RAG pipeline.

Provides a trait-based interface so the engine is not coupled to any specific embedding backend. In production you’ll typically wrap a Python subprocess or an HTTP API; in tests you can use FixedEmbedder.

Structs

FixedEmbedder

Deterministic embedder that always returns the same vector. Useful in unit tests that need an Embedder but don’t care about the values.

SubprocessEmbedder

Embedder that talks to a long-lived Python subprocess over stdin/stdout.

Traits

Embedder

Trait for converting text into dense float vectors.
