Struct OpenAiEmbeddingProvider 

pub struct OpenAiEmbeddingProvider { /* private fields */ }

OpenAI-compatible embedding provider

Works with OpenAI, Azure OpenAI, and any API that implements the /v1/embeddings endpoint.

Implementations

impl OpenAiEmbeddingProvider

pub fn new( api_key: impl Into<String>, model: impl Into<String>, dimension: usize, ) -> Result<Self>

Create a new OpenAI embedding provider

• api_key: API key for authentication
• model: Model name (e.g., “text-embedding-3-small”)
• dimension: Embedding dimension (e.g., 1536)

pub fn with_base_url( api_key: impl Into<String>, model: impl Into<String>, dimension: usize, base_url: impl Into<String>, ) -> Result<Self>

Create with a custom base URL (for Azure, local proxies, etc.)

Trait Implementations

impl Debug for OpenAiEmbeddingProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl EmbeddingProvider for OpenAiEmbeddingProvider

fn name(&self) -> &str

Provider name for logging

fn dimension(&self) -> usize

Embedding dimension (e.g., 1536 for OpenAI text-embedding-3-small)

fn embed<'life0, 'life1, 'async_trait>( &'life0 self, text: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Embedding>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Generate embedding for a single text

fn embed_batch<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, texts: &'life1 [&'life2 str], ) -> Pin<Box<dyn Future<Output = Result<Vec<Embedding>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Generate embeddings for multiple texts (batch)
