Invalid backend-neutral generation configuration or state transition.

Variants

AlreadyFinished

A token was committed after termination.

EmptyProposalBlock

A proposal transaction cannot be empty.

InvalidSpeculativeTransition

Proposal acceptance/rejection order was invalid.

IncompleteSpeculativeRound

No terminal outcome or replacement/bonus tail resolved the round.

OptimisticPrefixDiverged

Optimistic state was forked from a different prefix.

EmptyOptimisticBranch

An optimistic branch contained no proposals.

OptimisticBranchAlreadyPresent

A second optimistic branch was installed for one target transaction.

UnknownSpeculativeRequest

A speculative request identifier does not belong to this table.

Fields

index: usize

Requested stable insertion index.

ProposalCapacityExceeded

A promoted proposal block no longer fits the canonical request budget.

Fields

proposed: usize

Proposals retained by the promoted block.

capacity: usize

Current canonical proposal capacity.

ActiveSpeculativeRequests

A speculative request table was consumed before reaching terminal state.

MissingSpeculativeFinishReason

A terminal speculative request did not retain its canonical finish reason.

Fields

index: usize

Stable request insertion index.

ZeroDraftTokens

No assistant proposal may be generated per round.

NoBackendDraftCapacity

The selected backend cannot submit an assistant proposal.

InvalidTemperature(f32)

Temperature is NaN, infinite, or negative.

StochasticZeroTemperature

Stochastic sampling cannot use zero temperature.

InvalidMirostatTau(f32)

Mirostat V2 target surprise is non-finite or non-positive.

InvalidMirostatEta(f32)

Mirostat V2 adaptation rate is non-finite or non-positive.

InvalidTopK(i32)

Top-k is negative.

InvalidTopP(f32)

Top-p lies outside zero through one.

InvalidMinP(f32)

Min-p lies outside zero through one.

InvalidRepetitionPenalty(f32)

Repetition penalty is non-finite or non-positive.

InvalidFrequencyPenalty(f32)

Frequency penalty is non-finite.

InvalidPresencePenalty(f32)

Presence penalty is non-finite.

ZeroTokenBudget

An explicit token budget was zero.

ZeroInFlightVerifications

Scheduler cannot retain any target transaction.

TooManyLookaheadBlocks

Current scheduler supports no more than one lookahead block.

LookaheadWithoutBranchCapacity

Lookahead was enabled with no branch capacity.

ZeroAdaptiveLookaheadWindow

Adaptive lookahead needs a non-zero observation window.

StalledSpeculativeSchedule

Active requests expose no legal scheduler action.

InvalidSpeculativeStatusTransition

The requested speculative lifecycle edge is invalid.

Fields

from: SpeculativeRequestStatus

Current status.

to: SpeculativeRequestStatus

Requested status.

Trait Implementations

impl Clone for GenerationError

fn clone(&self) -> GenerationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenerationError

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

Formats the value using the given formatter.

impl Display for GenerationError

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

Formats the value using the given formatter.

impl Error for GenerationError

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 PartialEq for GenerationError

fn eq(&self, other: &GenerationError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
