Failures surfaced while selecting a route, driving an algorithm, or serving a model call.

Variants

TargetNotFound

A named target was not present in the configured target set.

Fields

target: ModelId

Missing target model id.

NoTargets

Routing was attempted without any configured targets.

AlgorithmError

An algorithm could not complete for an algorithm-specific reason.

Fields

message: String

Description of the algorithm failure.

Driver(DriverError)

The step-stream driver could not complete an operation.

MissingFinalResponse

An algorithm’s step stream ended without a terminal routing outcome.

ClientCall

A target’s protocol client failed while serving a routed request.

Fields

target: ModelId

Target whose client failed.

source: LlmClientError

Typed error supplied by the protocol-owned client trait.

CircuitOpen

A target was skipped because its endpoint circuit is open.

Fields

target: ModelId

Target whose endpoint is being skipped.

VgrTiersUnavailable

Both VGR serving tiers were unavailable for the same request.

Fields

local: Box<LibsyError>

Failure from the local attempt.

cloud: Box<LibsyError>

Failure from the terminal cloud completion.

External

A user extension or other foreign operation failed.

Fields

operation: &'static str

Short description of the operation that failed.

source: Box<dyn StdError + Send + Sync>

Original failure.

Implementations

impl LibsyError

pub fn client_call(target: impl Into<ModelId>, source: LlmClientError) -> Self

Wrap an error returned by the protocol-owned client trait.

pub fn external( operation: &'static str, source: impl StdError + Send + Sync + 'static, ) -> Self

Preserve a concrete foreign error with a description of the failed operation.

Trait Implementations

impl Debug for LibsyError

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

Formats the value using the given formatter.

impl Display for LibsyError

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

Formats the value using the given formatter.

impl Error for LibsyError

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<DriverError> for LibsyError

fn from(source: DriverError) -> Self

Converts to this type from the input type.
