Struct ChatGptClient 

pub struct ChatGptClient { /* private fields */ }

OpenAI chat completion client.

Implementations

impl ChatGptClient

pub fn new(api_key: &str, model: &str) -> Result<Self>

Create a new client. The API key is baked into the underlying reqwest::Client as a default header so it doesn’t need to be cloned per-request.

pub async fn chat(&self, messages: Vec<Message>) -> Result<String, LlmError>

Send a blocking chat completion request, returning the full response.

pub async fn chat_with_tools( &self, messages: Vec<Message>, tools: Option<&[ToolDefinition]>, ) -> Result<(Message, Option<String>), LlmError>

Non-streaming chat completion with tool support.

Returns the full assistant Message and the finish_reason. The agent loop inspects these to decide whether to execute tools or return the final answer.

pub fn chat_stream( &self, messages: Vec<Message>, ) -> impl Stream<Item = Result<String, LlmError>> + Send

Stream a chat completion, yielding content tokens as they arrive.

The returned stream is 'static – it clones the HTTP client and model name so callers don’t need to worry about lifetimes.

Trait Implementations

fn clone_from(&mut self, source: &Self)
