Enum Provider 

#[non_exhaustive]
pub enum Provider {
    Ollama,
    Voyage,
    OpenAi,
    Gemini,
}

Which embeddings backend a Client talks to.

#[non_exhaustive]: more providers can be added in a minor release, so match with a _ => arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ollama

A local Ollama server ({base_url}/api/embed, default http://localhost:11434). No API key, works offline; ignores EmbedKind.

Voyage

Voyage AI ({base_url}/embeddings, default https://api.voyageai.com/v1). Needs VOYAGE_API_KEY_ENV; honours input_type (EmbedKind) and output_dimension.

OpenAi

OpenAI, or any OpenAI-compatible /v1/embeddings endpoint (together.ai, vLLM, LocalAI, …) via a base_url override. Default https://api.openai.com/v1. Needs OPENAI_API_KEY_ENV; honours dimensions (ClientBuilder::output_dimension). Symmetric - ignores EmbedKind.

Gemini

Google Gemini (Generative Language API, {base_url}/models/{model}:batchEmbedContents, default https://generativelanguage.googleapis.com/v1beta). Needs GEMINI_API_KEY_ENV; maps EmbedKind to taskType and honours outputDimensionality.
