Struct Message 

pub struct Message {
    pub role: Role,
    pub content: Option<String>,
    pub name: Option<String>,
    pub tool_call_id: Option<String>,
    pub tool_calls: Option<Vec<ToolCall>>,
    pub reasoning_content: Option<String>,
    pub prefix: Option<bool>,
}

Fields

role: Role

default role is User

content: Option<String>

content 在 assistant 消息可能为 null（仅 tool_calls 时）

name: Option<String>

用于标识用户/函数名称（可选）

tool_call_id: Option<String>

当 role = “tool” 时必须提供，关联之前的工具调用 ID

tool_calls: Option<Vec<ToolCall>>

当 role = “assistant” 且模型请求调用工具时包含此字段

reasoning_content: Option<String>

模型推理过程的内容（仅在响应中可能包含）

prefix: Option<bool>

Beta 功能：设置此参数为 true，来强制模型在其回答中以此 assistant 消息中提供的前缀内容开始
