Enum EmbedderDefinition 

pub enum EmbedderDefinition {
    Precomputed,
    CandleBert {
        model: String,
    },
    CandleClip {
        model: String,
    },
    Openai {
        model: String,
    },
}

A declarative embedder definition stored in the schema.

Each variant maps to a concrete Embedder implementation. The type tag selects the variant; additional fields provide type-specific configuration.

API Key Handling

For embedders that require API keys (e.g. OpenAI), the key is read from an environment variable at engine initialization time, not stored in the schema.

Variants

Precomputed

Pre-computed vectors — no embedding is performed. Use this when vectors are computed externally and passed directly.

CandleBert

Candle-based BERT embedder for text embedding. Requires the embeddings-candle feature.

Fields

model: String

HuggingFace model ID (e.g. "sentence-transformers/all-MiniLM-L6-v2").

CandleClip

Candle-based CLIP multimodal embedder for text and image embedding. Requires the embeddings-multimodal feature.

Fields

model: String

HuggingFace model ID (e.g. "openai/clip-vit-base-patch32").

Openai

OpenAI API embedder for text embedding. Requires the embeddings-openai feature. The API key is read from the OPENAI_API_KEY environment variable.

Fields

model: String

OpenAI model name (e.g. "text-embedding-3-small").

Trait Implementations
