Struct OpenAIEmbeddingProvider 

pub struct OpenAIEmbeddingProvider { /* private fields */ }

OpenAI Embedding Provider

Implements EmbeddingProvider trait for generating embeddings via OpenAI API.

Implementations

impl OpenAIEmbeddingProvider

pub fn new(api_key: String, config: EmbeddingConfig) -> Result<Self>

Create a new OpenAI embedding provider

Arguments

• api_key - OpenAI API key
• config - Embedding configuration (model, dimension, etc.)

Example

let provider = OpenAIEmbeddingProvider::new(
    "sk-...".to_string(),
    EmbeddingConfig::openai_large(),
)?;

pub fn from_env() -> Result<Self>

Create provider from environment variables

Uses OPENAI_API_KEY for authentication and optionally OPENAI_EMBEDDING_MODEL to override the default model.

pub fn large(api_key: String) -> Result<Self>

Create provider with text-embedding-3-large (default, highest quality)

pub fn small(api_key: String) -> Result<Self>

Create provider with text-embedding-3-small (faster, lower cost)

pub fn ada(api_key: String) -> Result<Self>

Create provider with text-embedding-ada-002 (legacy)
