Enum RetrieverError 

#[non_exhaustive]
pub enum RetrieverError {
    StoreError(VectorStoreError),
    EmbeddingError(String),

检索器错误类型

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StoreError(VectorStoreError)

向量存储错误

EmbeddingError(String)

嵌入错误

LlmError(String)

LLM 拆解失败(调用失败 / 输出无法解析)。SelfQuery(S4) 用。

InvalidFilter(String)

过滤器引用了 allowed_attributes 白名单外的字段(SelfQuery)。 显式报错,绝不静默丢弃后回落无过滤检索——那会让本该被过滤排除的 数据被返回(数据面过曝)。

NoResults

无结果

Trait Implementations

impl Debug for RetrieverError

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

Formats the value using the given formatter.

impl Display for RetrieverError

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

Formats the value using the given formatter.

impl Error for RetrieverError

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.

impl From<VectorStoreError> for RetrieverError

fn from(e: VectorStoreError) -> Self

Converts to this type from the input type.
