Enum EmbeddingError 

pub enum EmbeddingError {
    HttpError(String),
    ApiError(String),
    ParseError(String),
    Config(String),
    EmptyInput,
    BatchMismatch {
        expected: usize,
        actual: usize,
    },
    EmptyVectorInBatch,
}

Embedding model trait — re-exported from lc-embeddings.

Used by vector store implementations that need to embed documents on the fly (e.g., Pinecone’s upsert method). Embedding error type

Variants

HttpError(String)

HTTP request error

ApiError(String)

API error

ParseError(String)

Parse error

Config(String)

配置错误（如 API key 为空、模型维度未知）——构造期 fail fast。

EmptyInput

Empty input

BatchMismatch

批量 embedding 数量错位：请求 N 条文本，服务端返回的向量数量或 index 超出了预期范围（某 chunk 少返回/乱序导致）。

P0-1: 拒绝静默错数据——绝不把缺失向量当成“不相似“。

Fields

expected: usize

actual: usize

EmptyVectorInBatch

批量 embedding 中某条文本未取到向量（服务端返回量 < 请求量）。

P0-1: 拒绝静默空向量——缺失即显式报错，而非留下零向量。

Trait Implementations

impl Debug for EmbeddingError

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

Formats the value using the given formatter.

impl Display for EmbeddingError

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

Formats the value using the given formatter.

impl Error for EmbeddingError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
