Enum AssistantBlock 

pub enum AssistantBlock {
    Text {
        text: String,
    },
    Reasoning {
        text: String,
        signature: Option<String>,
    },
    ToolCall {
        id: ToolCallId,
        name: String,
        arguments: Value,
    },
}

Assistant 专用内容块 — 比基础块多了推理和工具调用。

编译期保证只有 Assistant 消息可以包含 ToolCall 和 Reasoning。

Trait Implementations

impl Clone for AssistantBlock

fn clone(&self) -> AssistantBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssistantBlock

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AssistantBlock

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AssistantBlock

fn eq(&self, other: &AssistantBlock) -> 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 AssistantBlock

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
