Enum CompletionError 

pub enum CompletionError {
    RequestError(Box<dyn Error + Send + Sync + 'static>),
    ResponseError(String),
    ProviderError {
        message: String,
        class: ErrorClass,
    },
    JsonError(Error),
}

Error invoking a completion model.

Variants

RequestError(Box<dyn Error + Send + Sync + 'static>)

Error building the completion request.

ResponseError(String)

Error parsing the completion response.

ProviderError

Error returned by the completion model provider, with the provider’s retry classification.

Fields

message: String

class: ErrorClass

JsonError(Error)

JSON (de)serialization error.

Implementations

impl CompletionError

pub fn provider(class: ErrorClass, message: impl Into<String>) -> Self

A provider error with an explicit retry classification.

pub fn class(&self) -> ErrorClass

How callers should treat this error.

• RequestError and JsonError are our side failing to build or parse — retrying the same request cannot help (ErrorClass::Fatal).
• ResponseError is a transport/framing failure while reading the response — typically transient.
• ProviderError carries the provider’s own classification.

Trait Implementations

impl Debug for CompletionError

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

Formats the value using the given formatter.

impl Display for CompletionError

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

Formats the value using the given formatter.

impl Error for CompletionError

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<Box<dyn Error + Send + Sync>> for CompletionError

fn from(source: Box<dyn Error + Send + Sync + 'static>) -> Self

Converts to this type from the input type.

impl From<Error> for CompletionError

fn from(source: Error) -> Self

Converts to this type from the input type.
