Enum DriverLoadError 

pub enum DriverLoadError {
    LibraryNotFound {
        candidates: Vec<String>,
        last_error: String,
    },
    SymbolNotFound {
        symbol: &'static str,
        reason: String,
    },
    InitializationFailed {
        code: u32,
    },
    UnsupportedPlatform,
}

Errors that can occur while dynamically loading libcuda.so / nvcuda.dll.

Variants

LibraryNotFound

The CUDA driver library was not found on the system.

Fields

candidates: Vec<String>

Library names that were attempted.

last_error: String

OS-level error from the last attempt.

SymbolNotFound

The shared library was loaded but a required symbol was missing.

Fields

symbol: &'static str

Name of the missing symbol (e.g. "cuInit").

reason: String

OS-level error description.

InitializationFailed

The CUDA driver library loaded and all symbols resolved, but cuInit(0) returned a non-zero error code.

This typically happens when there is no CUDA-capable GPU installed (CUDA_ERROR_NO_DEVICE = 100) or when the installed driver is incompatible with the hardware.

Fields

code: u32

Raw CUDA error code returned by cuInit.

UnsupportedPlatform

CUDA is not supported on this operating system (e.g. macOS).

Trait Implementations

impl Debug for DriverLoadError

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

Formats the value using the given formatter.

impl Display for DriverLoadError

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

Formats the value using the given formatter.

impl Error for DriverLoadError

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.
