Enum RuntimeError 

pub enum RuntimeError {
    Config(String),
    ProviderNotFound(String),
    CapabilityMismatch(String),
    Load(String),
    ApiError(String),
    InferenceError(String),
    RateLimited,
    Unauthorized,
    Timeout,
    Unavailable,
}

Unified error type covering configuration, loading, inference, and transport failures.

Variants are intentionally coarse-grained so that callers can match on error category (e.g. retryable vs permanent) rather than on provider-specific details.

Variants

Config(String)

Invalid or missing configuration (bad alias format, unknown option, etc.).

ProviderNotFound(String)

The requested provider ID is not registered with the runtime.

CapabilityMismatch(String)

A model was requested for a task the provider does not support.

Load(String)

Model loading or initialization failed (download, weight parsing, etc.).

ApiError(String)

An HTTP or transport-level error from a remote provider.

InferenceError(String)

An error during model inference (tokenization, forward pass, etc.).

RateLimited

The remote API returned HTTP 429 (too many requests).

Unauthorized

The remote API returned HTTP 401/403 (bad or missing credentials).

Timeout

The operation exceeded its configured timeout.

Unavailable

The service is currently unavailable (HTTP 5xx, circuit breaker open, etc.).

Implementations

impl RuntimeError

pub fn is_retryable(&self) -> bool

Returns true for transient errors that may succeed on retry: RateLimited, Timeout, and Unavailable.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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.
