ToolCall

All Implemented Interfaces:
```
public abstract class ToolCall
extends JsonSerializable
                    
```
A predicted server-side `ToolCall` returned from the model.
This message contains information about a tool that the model wants to invoke. The client is NOT expected to execute this `ToolCall`. Instead, the client should pass this `ToolCall` back to the API in a subsequent turn within a `Content` message, along with the corresponding `ToolResponse`.
