Error types for backend operations.

Variants

NotRunning

Backend server is not running.

ModelNotFound(String)

Model not found in registry or locally.

AlreadyLoaded(String)

Model is already loaded.

InsufficientMemory

Insufficient GPU/system memory.

NetworkError(String)

Network error during pull/API call.

ProcessError(String)

Process management error.

BackendSpecific(String)

Backend-specific error.

MissingApiKey(String)

Missing API key for cloud provider.

ApiError

API returned an error response.

Fields

status: u16

HTTP status code.

message: String

Error message from API.

ParseError(String)

Failed to parse API response.

LoadError(String)

Model loading failed.

InferenceError(String)

Inference failed.

InvalidConfig(String)

Invalid model configuration.

StorageError(String)

Storage/filesystem error.

DownloadError(String)

Download failed.

ChecksumError

Checksum verification failed.

Fields

expected: String

Expected checksum.

actual: String

Actual checksum.

Implementations

impl BackendError

pub const fn is_retryable(&self) -> bool

Returns true if this error is transient and the operation should be retried.

Retryable errors include network failures and temporary backend unavailability. Non-retryable errors include model not found, insufficient memory, etc.

pub fn is_auth_error(&self) -> bool

Returns true if this is an authentication/authorization error.

Trait Implementations

impl Clone for BackendError

fn clone(&self) -> BackendError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendError

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

Formats the value using the given formatter.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

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<NativeError> for BackendError

fn from(err: NativeError) -> Self

Converts to this type from the input type.

impl PartialEq for BackendError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for BackendError
