Add function call request param

[DaviRain-Su]

close: #72
#76

• Remove example/Cargo.toml, add to root Cargo.toml
• Add function-call example get_current_weather

I would also update the readme to add function as feature

I am currently writing an example code for function calls, but I encountered an issue with the error: JSONDeserialize(Error("invalid type: null, expected a string", line: 11, column: 23)). I need some help to resolve this.

Hi @DaviRain-Su, Thank you for the PR and adding example for this new feature - its a great way to test it.

Here are some hints for you to debug this further:

• see the updated upstream OpenAPI spec and match it with Rust type in code
• setup tracing_subscriber so that tracing::error!( ... ) can log the actualy json payload causing deserializtion error. examples/rate-limit-completions has an example - however you might need to change log level.

Hope this helps

Successfully added an example that can use function calls.

It appears that naming does not adheres to OpenAPI spec.

For example ChatCompletionFunctions , Please see the names of new types in this PR #73 - that's the unfortunate part of having types hand written instead of having it auto generated. That said, naming should be consistent with rest of the project

For background: all/majority of types in types.rs are named based on OpenAPI component schema.

[DaviRain-Su]

Have fix all.

function_call in ChatCompletionRequestMessage and ChatCompletionResponseMessage can also be a struct with name and arguments - I'll take care of it before publishing.

Thank you for addressing the comments, nice work on the new example!
