Overview

• FunctionDescription: Describes a callable function with a name, optional description, and a JSON Schema for its parameters.
• Tool: An enum representing available types of tools. Currently, only function‑type tools are supported.
• FunctionCall: Represents the details of a requested tool call including the function name and JSON‑encoded arguments.
• ToolCall: Captures the tool call details as returned by the API, including a unique identifier and the associated function call details.
• ToolChoice: Represents the possible outcomes when the model must select a tool (for example, “none”, “auto”, or a specific function choice).
• FunctionName: A simple structure to represent a function name for tool selection.
