Enum RetrieverError 

#[non_exhaustive]
pub enum RetrieverError {
    StoreError(VectorStoreError),
    EmbeddingError(String),
    LlmError(String),
    InvalidFilter(String),
    NoResults,
}

Retriever error type

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)

Vector store error

EmbeddingError(String)

Embedding error

LlmError(String)

LLM breakdown failure (call failed / output unparseable). Used by SelfQuery (S4).

InvalidFilter(String)

The filter references a field outside the allowed_attributes whitelist (SelfQuery). Errors out explicitly, never silently falls back to unfiltered retrieval — that would return data that should have been filtered out (data-plane over-exposure).

NoResults

No results

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.
