Example of multiple function calls

[ysimonson]

GPT-4 Turbo supports multiple function calls, but I couldn't any examples of this in async-openai yet. It took me a little while to stitch together how to do this since it's a bit divergent from single function calls, so maybe this minimal demonstration will be helpful to someone else:

let request = CreateChatCompletionRequestArgs::default()
    .model("gpt-4-1106-preview")
    .messages([
        ChatCompletionRequestUserMessageArgs::default()
            .content(prompt)
            .build()?
            .into(),
        ChatCompletionRequestSystemMessageArgs::default()
            .content(SYSTEM_PROMPT)
            .build()?
            .into(),
    ])
    .max_tokens(512u16)
    .stream(false)
    .tools([
        ChatCompletionToolArgs::default()
            .r#type(ChatCompletionToolType::Function)
            .function(
                // ... build ChatCompletionFunctions here ...
            )
            .build()?,
        ...
    ])
    .build()?;

if let Some(tool_calls) = response_message.tool_calls {
    tool_calls
        .into_iter()
        .map(|tool_call| ...)
        .collect()?;
}

Seems like this was addressed in #153? yes?

Yup!
