Errors returned while configuring or calling the provider endpoint.

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.

InvalidConfiguration(InvalidConfiguration)

A local configuration value violated its invariant.

Transport

The HTTP exchange failed before a complete response body was received.

Fields

source: Error

The underlying HTTP client failure.

Timeout

The configured request deadline elapsed.

Fields

duration: Duration

Configured whole-request timeout.

source: Error

The underlying HTTP client timeout.

Provider

The provider returned a non-success HTTP status.

Fields

status: StatusCode

The HTTP status returned by the provider.

failure: ProviderFailure

A sanitized, typed representation of the provider failure.

InvalidResponse

A success response did not match the supported typed contract.

Fields

source: Error

The JSON decoding failure. The response body itself is not retained.

ResponseTooLarge

The response body exceeded the configured safety limit.

Fields

limit_bytes: usize

Maximum number of response bytes accepted by this client.

MissingChoice

A completion did not contain any choices.

MissingToolCall

A tool-call completion did not contain a tool call.

MissingContent

A final completion did not contain text content.

Tool(ToolError)

A typed tool contract was invalid or could not decode provider output.

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 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 From<InvalidConfiguration> for Error

fn from(source: InvalidConfiguration) -> Self

Converts to this type from the input type.

impl From<ToolError> for Error

fn from(source: ToolError) -> Self

Converts to this type from the input type.
