Error returned by the Metal transcode accelerator.

Variants

MetalUnavailable

Metal is unavailable on this host or target.

UnsupportedJob(&'static str)

The request is outside the current Metal implementation.

Runtime(MetalRuntimeFailure)

Metal runtime creation or device execution failed with its diagnostic retained.

MetalSupport

A shared Metal resource operation failed with its typed source retained.

Fields

operation: &'static str

Logical Metal operation that failed.

source: MetalSupportError

Typed shared-support failure.

Kernel(&'static str)

A validated Metal result violated an internal kernel contract.

HostAllocationTooLarge

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

Fields

requested: usize

Requested byte count, saturated on overflow.

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.

DeviceAllocationTooLarge

A codec-owned Metal allocation exceeds the shared transcode safety limit.

Fields

requested: usize

Requested byte count, saturated on overflow.

cap: usize

Maximum permitted byte count.

what: &'static str

Logical allocation purpose.

DeviceAllocationFailed

Metal returned no buffer for a bounded device allocation.

Fields

requested: usize

Requested byte count.

what: &'static str

Logical allocation purpose.

Trait Implementations

impl Debug for MetalTranscodeError

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

Formats the value using the given formatter.

impl Display for MetalTranscodeError

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

Formats the value using the given formatter.

impl Error for MetalTranscodeError

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<MetalTranscodeError> for TranscodeStageError

fn from(error: MetalTranscodeError) -> Self

Converts to this type from the input type.
