Struct Message 

pub struct Message {
    pub role: Role,
    pub content: String,
    pub tool_calls: Vec<ToolCall>,
    pub tool_results: Vec<ToolCallResult>,
    pub timestamp: DateTime<Utc>,
    pub content_parts: Vec<ContentPart>,
}

A message in a bout (conversation).

Fields

role: Role

Text content of the message (may be empty for tool-only messages).

tool_calls: Vec<ToolCall>

Tool calls requested by the assistant.

tool_results: Vec<ToolCallResult>

Results from tool executions (for role = Tool).

timestamp: DateTime<Utc>

When the message was created.

content_parts: Vec<ContentPart>
