Enum RandError 

pub enum RandError {
    Cuda(CudaError),
    PtxGeneration(PtxGenError),
    InvalidSize(String),
    InvalidSeed(String),
    InvalidParameter(String),
    UnsupportedDistribution(String),
    InternalError(String),
}

RNG-specific error type.

Every fallible RNG operation returns RandResult<T> which uses this enum as its error variant.

Variants

Cuda(CudaError)

A CUDA driver call failed.

PtxGeneration(PtxGenError)

PTX kernel source generation failed.

InvalidSize(String)

The requested output size is invalid (e.g., zero elements, or not a multiple of the engine’s natural output width).

InvalidSeed(String)

The provided seed value is invalid.

InvalidParameter(String)

One or more distribution parameters are invalid.

UnsupportedDistribution(String)

The requested distribution is not supported for this engine or precision combination.

InternalError(String)

An internal error that should not occur under normal operation.

Trait Implementations

impl Debug for RandError

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

Formats the value using the given formatter.

impl Display for RandError

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

Formats the value using the given formatter.

impl Error for RandError

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<CudaError> for RandError

fn from(source: CudaError) -> Self

Converts to this type from the input type.

impl From<PtxGenError> for RandError

fn from(source: PtxGenError) -> Self

Converts to this type from the input type.
