Struct OpenAIProvider 

pub struct OpenAIProvider {
    model: String,
    dims: usize,
}

Embedding provider using the OpenAI API.

Calls the POST /v1/embeddings endpoint with the configured model. Requires the OPENAI_API_KEY environment variable to be set.

Features

• Batched embedding (multiple texts per API call)
• Exponential backoff retry for rate limits and server errors
• Configurable timeout and max retries

Fields

model: String

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

dims: usize

Vector dimensionality (e.g. 1536).

Implementations

impl OpenAIProvider

pub fn new(config: &EmbeddingConfig) -> Result<Self>

Create a new OpenAI provider from configuration.

Errors

Returns an error if model or dims is not set in config, or if OPENAI_API_KEY is not in the environment.

Trait Implementations

impl EmbeddingProvider for OpenAIProvider

fn model_name(&self) -> &str

Returns the model identifier (e.g. "text-embedding-3-small").

fn dims(&self) -> usize

Returns the embedding vector dimensionality (e.g. 1536).
