Struct ChatStreamResponse 

pub struct ChatStreamResponse {
    pub id: Option<String>,
    pub created: Option<u64>,
    pub model: Option<String>,
    pub choices: Vec<StreamChoice>,
    pub usage: Option<Usage>,
}

Represents a single streaming chunk from the chat API.

This struct contains a portion of the complete response that arrives as part of an SSE stream. Multiple chunks are typically received and assembled to form the complete response.

Fields

• id - Unique identifier for the streaming session (optional)
• created - Unix timestamp when the chunk was created (optional)
• model - Name of the model generating the response (optional)
• choices - Array of streaming choices, usually containing one item
• usage - Token usage statistics, typically only on final chunk

Fields

id: Option<String>

Unique identifier for the streaming session.

May be a string or number in the wire format, converted to Option<String>.

created: Option<u64>

Unix timestamp indicating when the chunk was created.

model: Option<String>

Name of the AI model generating the response.

choices: Vec<StreamChoice>

Array of streaming choices, typically containing one item per chunk.

Each choice contains a delta with partial content updates.

usage: Option<Usage>

Token usage statistics.

This field typically appears only on the final chunk of the stream, providing information about prompt and completion token counts.
