Enum GpuError 

pub enum GpuError {
    ContextPoisoned(String),
    OutOfMemory(String),
    Unrecoverable(String),
    GpuRefStale(&'static str),
    Driver(String),
    Cublas(String),
    LibraryError {
        lib: &'static str,
        msg: String,
    },
    Timeout,
}

Variants

ContextPoisoned(String)

CUDA context is in a sticky-error state (§5.3). Triggers ContextActor restart and a generation bump on DeviceState.

OutOfMemory(String)

Allocation failed but the context is still usable. Supervisor Resumes the actor.

Unrecoverable(String)

Hardware fault or repeated poisoning past the retry budget.

GpuRefStale(&'static str)

GpuRef::access() was called on a buffer whose context was rebuilt or whose DeviceActor is shutting down (§5.8).

Driver(String)

Cublas(String)

👎Deprecated: use GpuError::LibraryError { lib: “cublas”, msg } instead

cuBLAS-specific error. Retained for back-compat — new library actors should emit GpuError::LibraryError with lib = "cublas" instead. Will be removed in a future release.

LibraryError

Generic library error tagged with the originating CUDA library name (e.g. "cudnn", "cufft", "curand", "cusolver", "cublaslt", "nvrtc", "nccl"). Callers that need to discriminate library failures match on lib.

Fields

lib: &'static str

msg: String

Timeout

Implementations

impl GpuError

pub fn lib(lib: &'static str, msg: impl Into<String>) -> Self

Construct a tagged library error.

impl GpuError

pub fn panic_message(&self) -> String

Format suitable for panicking out of an actor handler so that the atomr supervisor’s decider can route it.

Trait Implementations

impl Debug for GpuError

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

Formats the value using the given formatter.

impl Display for GpuError

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

Formats the value using the given formatter.

impl Error for GpuError

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.
