Struct OpenAIToolCall 

pub struct OpenAIToolCall {
    pub id: String,
    pub call_type: String,
    pub function: OpenAIFunction,
}

OpenAI tool call representation in API messages.

Represents a request from the model to execute a specific function/tool. This is the wire format used in the OpenAI API, distinct from the internal ToolUseBlock representation.

Structure

Each tool call has:

• A unique ID for correlation with results
• A type (always “function” in current OpenAI API)
• Function details (name and arguments)

Example JSON

{
  "id": "call_abc123",
  "type": "function",
  "function": {
    "name": "get_weather",
    "arguments": "{\"location\":\"San Francisco\"}"
  }
}

Fields

id: String

Unique identifier for this tool call.

Generated by the model. Used to correlate tool results back to this specific call.

call_type: String

Type of the call (always “function” in current API).

The rename attribute ensures this serializes as "type" in JSON since type is a Rust keyword.

function: OpenAIFunction

Function/tool details (name and arguments).
