Crate fathomdb_embedder 

FathomDB embedder — the built-in embedder implementations behind the fathomdb-embedder-api trait.

An internal workspace crate. To use FathomDB, depend on the fathomdb facade crate and opt into the default embedder at open; you do not need to name this crate. To write your OWN embedder, implement the trait in fathomdb-embedder-api — which pulls in no model runtime — rather than depending on this one.

The default embedder is bge-small-en-v1.5 (384-dim) running on a pure-Rust candle-transformers BERT in process: no Python, no sidecar. It is gated behind the default-embedder cargo feature so a consumer who never uses it pays neither the dependency nor the binary-size cost, and it is opt-in per engine at open — a fresh engine has no embedder configured.

On first use the loader downloads and sha256-verifies the weights into the platform cache; that is the crate’s only network access, and it happens only when the feature is on and the embedder is opted into.
