Enum MessageBlock 

pub enum MessageBlock {
    Text {
        text: String,
    },
    Image {
        source: ImageSource,
    },
    ImageUrl {
        image_url: ImageUrl,
    },
}

消息内容块

一条消息可以包含多个内容块，支持文本、图片等多模态内容

示例

use llm_connector::types::MessageBlock;

// 文本块
let text = MessageBlock::text("Hello, world!");

// 图片块（Base64）
let image = MessageBlock::image_base64("image/jpeg", "base64_data...");

// 图片块（URL）
let image_url = MessageBlock::image_url("https://example.com/image.jpg");

Implementations

impl MessageBlock

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

创建文本块

示例

use llm_connector::types::MessageBlock;

let block = MessageBlock::text("Hello, world!");

pub fn image_base64( media_type: impl Into<String>, data: impl Into<String>, ) -> Self

创建 Base64 图片块（Anthropic 格式）

参数

• media_type: 媒体类型，如 “image/jpeg”, “image/png”
• data: Base64 编码的图片数据

示例

use llm_connector::types::MessageBlock;

let block = MessageBlock::image_base64(
    "image/jpeg",
    "iVBORw0KGgoAAAANSUhEUgA..."
);

pub fn image_url_anthropic(url: impl Into<String>) -> Self

创建图片 URL 块（Anthropic 格式）

示例

use llm_connector::types::MessageBlock;

let block = MessageBlock::image_url_anthropic("https://example.com/image.jpg");

pub fn image_url(url: impl Into<String>) -> Self

创建图片 URL 块（OpenAI 格式）

示例

use llm_connector::types::MessageBlock;

let block = MessageBlock::image_url("https://example.com/image.jpg");

pub fn image_url_with_detail( url: impl Into<String>, detail: impl Into<String>, ) -> Self

创建图片 URL 块（OpenAI 格式，带 detail 参数）

参数

• url: 图片 URL
• detail: 图片细节级别，可选值: “auto”, “low”, “high”

示例

use llm_connector::types::MessageBlock;

let block = MessageBlock::image_url_with_detail(
    "https://example.com/image.jpg",
    "high"
);

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

获取文本内容（如果是文本块）

示例

use llm_connector::types::MessageBlock;

let block = MessageBlock::text("Hello");
assert_eq!(block.as_text(), Some("Hello"));

let image = MessageBlock::image_url("https://...");
assert_eq!(image.as_text(), None);

pub fn is_text(&self) -> bool

判断是否为文本块

pub fn is_image(&self) -> bool

判断是否为图片块

Trait Implementations

impl Clone for MessageBlock

fn clone(&self) -> MessageBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageBlock

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageBlock

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageBlock

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
