Error returned by the CUDA transcode accelerator.

Variants

CudaUnavailable

CUDA is unavailable on this host or the kernels were not built.

UnsupportedJob(&'static str)

The request is outside the current CUDA implementation.

Kernel(&'static str)

A validated CUDA result violated an internal kernel contract.

HostAllocationTooLarge

A codec-owned host allocation exceeds the transcode safety limit.

Fields

requested: usize

Requested byte count, saturated when size arithmetic overflowed.

cap: usize

Maximum permitted byte count.

what: &'static str

Logical allocation purpose.

HostAllocationFailed

A bounded codec-owned host allocation could not be reserved.

Fields

requested: usize

Requested byte count.

what: &'static str

Logical allocation purpose.

Runtime(CudaRuntimeFailure)

CUDA runtime or kernel execution failed with the backend diagnostic retained as an error source.

Trait Implementations

impl Debug for CudaTranscodeError

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

Formats the value using the given formatter.

impl Display for CudaTranscodeError

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

Formats the value using the given formatter.

impl Error for CudaTranscodeError

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<CudaTranscodeError> for TranscodeStageError

fn from(error: CudaTranscodeError) -> Self

Converts to this type from the input type.
