Enum OpenAIContent 

pub enum OpenAIContent {
    Text(String),
    Parts(Vec<OpenAIContentPart>),
}

OpenAI API message format for serialization.

This struct represents the wire format for messages when communicating with OpenAI-compatible APIs. It differs from the internal Message type to accommodate the specific serialization requirements of the OpenAI API.

Key Differences from Internal Message Type

• Content is a flat string rather than structured blocks
• Tool calls are represented in OpenAI’s specific format
• Supports both sending tool calls (via tool_calls) and tool results (via tool_call_id)

Serialization

Optional fields are skipped when None to keep payloads minimal.

Usage

This type is typically created by the SDK internally when converting from Message to API format. Users rarely need to construct these directly.

OpenAI Content Format

OpenAI content format supporting both string and array.

For backward compatibility, text-only messages use string format. Messages with images use array format with multiple content parts.

Variants

Text(String)

Simple text string (backward compatible)

Parts(Vec<OpenAIContentPart>)

Array of content parts (text and/or images)
