Module embedder 

Host-agnostic Embedder trait, joint embedding output, and error helpers.

Structs

JointEmbeddingOutput

Output container for single-pass joint multi-modal / BGE-M3 embedding.

SparseEmbedder

Local sparse-only helper (no dense model). Default English pipeline only — hosts needing other languages use Bm25TextConfig / Bm25Pipeline directly.

Traits

Host-agnostic embedding backend.

EmbedderBound

Send/Sync bound helper for Embedder implementations on native targets.

Error when a dense model is requested that this embedder cannot satisfy.

image_unsupported_error

Error when image embedding is requested but the host has no image path.

multi_unsupported_error

Error when multi-vector embedding is requested but the host has no multi path.

sparse_model_unsupported_error

Error when a sparse model is requested that this embedder cannot satisfy.
