Core error type for Platonic primitives.

Variants

EmptyIdentifier(&'static str)

Identifier constructor received an empty value.

ContextBudgetExceeded

A token budget would be exceeded.

Fields

used: u32

Estimated tokens, saturated at u32::MAX for reporting.

budget: u32

Maximum tokens allowed by the context pack.

InvalidCompactionRange

A context compaction range was empty or reversed.

Fields

start: u64

Zero-based start position in the prior-turn list.

end_exclusive: u64

Exclusive end position in the prior-turn list.

SequenceMismatch

A recorded event sequence number was not the expected next value.

Fields

expected: u64

Next contiguous sequence number required by the run state.

actual: u64

Sequence number carried by the rejected record.

RunIdMismatch

An event for one run was applied to another run.

Fields

expected: String

Run already bound to the state machine.

actual: String

Run named by the rejected event.

InvalidTransition

An event was not legal in the current run phase.

Fields

phase: &'static str

Stable diagnostic name of the phase that rejected the event.

event: &'static str

Stable diagnostic name of the rejected event.

StepMismatch

A model response did not match the pending model request.

Fields

expected: u32

Step of the pending model request.

actual: u32

Step carried by the rejected event.

TurnMismatch

A turn-scoped event did not match the pending turn.

Fields

expected: String

Turn currently awaiting the event.

actual: String

Turn named by the rejected event.

TurnReused

A new turn reused an earlier turn id from the same run.

Fields

turn_id: String

Reused turn identifier.

EmptyToolProposalsRejectionReason

A whole-batch tool proposal rejection omitted its explanation.

ToolCallMismatch

A tool event did not match the pending tool call.

Fields

expected: String

Tool call currently awaiting the event.

actual: String

Tool call named by the rejected event.

ToolCallReused

A validated tool call reused an earlier call id from the same run.

Fields

call_id: String

Reused tool-call identifier.

UnproposedToolCall

A validated tool call did not match any pending model proposal.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

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

Equality operator ==.

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

Inequality operator !=.
