Failure returned while completing a model request.

Variants

Request(Box<dyn Error + Send + Sync>)

The provider request or response decoding failed.

InvalidResponse

The provider returned a successful response without assistant content.

IncompleteResponse

The provider stopped before completing the model response.

Fields

reason: String

Provider-specific reason generation stopped.

ResponseBodyTooLarge

The successful provider response body exceeds the adapter safety limit.

UnsupportedOutputSchema

The provider cannot represent the requested output schema.

Fields

reason: String

Provider-specific reason the schema cannot be represented.

ResponseContentTooLarge

The decoded provider response content exceeds the harness safety limit.

InvalidJson

The provider returned malformed JSON for a structured request.

Fields

reason: String

JSON parser diagnostic without the raw response body.

SchemaViolation

The returned JSON does not conform to the requested schema.

Fields

path: String

Bounded JSON Pointer-like path to the invalid value, or $ for the root.

reason: String

Validator diagnostic for the failed constraint.

MissingToolCall

The provider returned tool calls without any call entries.

MultipleToolCalls

The provider returned more than the single supported call.

ToolCallWithContent

A tool-call response also contained terminal assistant content.

TerminalResponseWithToolCalls

A terminal response also contained native tool calls.

UnsupportedToolType

The provider returned an unsupported tool-call type.

Fields

kind: String

Provider tool type that is not a native function.

UnsupportedToolName

The provider returned an unsupported or unadvertised native function.

Fields

name: String

Native function name that was not advertised for the request.

InvalidToolArguments

The provider returned malformed or invalid native function arguments.

Fields

reason: String

Bounded parser or validation diagnostic.

Implementations

impl ModelError

pub fn request(error: impl Error + Send + Sync + 'static) -> Self

Wraps a provider transport or response-decoding failure.

Trait Implementations

impl Debug for ModelError

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

Formats the value using the given formatter.

impl Display for ModelError

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

Formats the value using the given formatter.

impl Error for ModelError

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<ModelError> for TurnError

fn from(source: ModelError) -> Self

Converts to this type from the input type.
