Enum ContentBlock 

pub enum ContentBlock {
    Text(TextBlock),
    Thinking(ThinkingBlock),
    Image {
        source: ImageSource,
    },
    ToolCall(ToolCall),
}

内容块 — Message 和 ChatResponse 的基本组成单元。 核心层极简，无 provider 特有标记。

Implementations

impl ContentBlock

pub fn text(s: impl Into<String>) -> Self

创建纯文本块。接受 &str、String。

pub fn text_with_cache(s: String, cache: CacheControl) -> Self

创建带缓存标记的文本块。

pub fn as_text(&self) -> Option<&str>

pub fn flatten_text(blocks: &[ContentBlock]) -> String

将多个 ContentBlock 拼接为纯文本，忽略非 Text 类型和 cache_control。

用于不支持 cache_control 的 Provider（OpenAI、Google）。 所有 Provider 共享同一份实现，避免各自拼接。

分隔符为 \n\n，与 Anthropic 块之间的隐式换行行为一致。

Trait Implementations

impl Clone for ContentBlock

fn clone(&self) -> ContentBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentBlock

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContentBlock

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContentBlock

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
