Struct EmbeddingConfig 

pub struct EmbeddingConfig {
    pub provider: String,
    pub model: Option<String>,
    pub dims: Option<usize>,
    pub batch_size: usize,
    pub max_retries: u32,
    pub timeout_secs: u64,
    pub url: Option<String>,
}

Embedding provider configuration.

Controls which embedding provider is used and its parameters. When provider = "disabled", no embeddings are generated and semantic/hybrid search modes will return errors.

Providers

Provider	Description
"disabled"	No embeddings (default)
"openai"	OpenAI API (text-embedding-3-small, etc.)
"ollama"	Local Ollama instance (nomic-embed-text, etc.)
"local"	Built-in models via fastembed (primary) or tract (musl/Intel Mac) (all-minilm-l6-v2, etc.)

When using "openai", the OPENAI_API_KEY environment variable must be set. When using "ollama", an Ollama instance must be running (default: http://localhost:11434). When using "local", the model is downloaded on first use and cached in ~/.cache/huggingface/.

Fields

provider: String

Provider name: "disabled", "openai", "ollama", or "local". Default: "disabled".

model: Option<String>

Embedding model name (e.g. "text-embedding-3-small", "nomic-embed-text", "all-minilm-l6-v2"). Required for openai and ollama; optional for local (defaults to "all-minilm-l6-v2").

dims: Option<usize>

Embedding vector dimensionality (e.g. 1536 for text-embedding-3-small). Required for openai and ollama; auto-detected for local.

batch_size: usize

Number of texts to embed per batch. Default: 64.

max_retries: u32

Maximum retry attempts for transient API errors. Default: 5.

timeout_secs: u64

HTTP timeout per request in seconds. Default: 30.

url: Option<String>

Base URL for Ollama API. Default: "http://localhost:11434".

Implementations

impl EmbeddingConfig

pub fn is_enabled(&self) -> bool
