Struct ChatMessage 

pub struct ChatMessage {
    pub role: MessageRole,
    pub content: Vec<ContentPart>,
}

A single message in a chat conversation.

Implements Default for forward-compatible struct-update syntax. Prefer the ChatMessage::system / ::user / ::assistant / ::tool constructors for clarity.

Fields

content: Vec<ContentPart>

Content parts (text, images). Serializes as a plain string when containing a single text part for backward compatibility.
