Struct AssistantMessage 

pub struct AssistantMessage {
    pub id: MessageId,
    pub content: Vec<AssistantBlock>,
    pub model: String,
    pub provider: String,
    pub finish_reason: FinishReason,
    pub usage: Option<Usage>,
    pub timestamp: DateTime<Utc>,
}

LLM 回复消息。

直接携带 model、provider、usage 等上下文信息， 便于多模型场景下追踪每轮回复的来源和开销。

model: String

使用的模型标识（如 "gpt-4o", "claude-sonnet-4-20250514"）

provider: String

Provider 标识（如 "openai", "anthropic"）

finish_reason: FinishReason

停止原因

usage: Option<Usage>

Token 用量统计

timestamp: DateTime<Utc>

Trait Implementations

impl Clone for AssistantMessage

fn clone(&self) -> AssistantMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AssistantMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AssistantMessage

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AssistantMessage

fn eq(&self, other: &AssistantMessage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AssistantMessage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
