        expected: BackendKind,
        actual: BackendKind,

}

Error returned by resident transcode handoff descriptor constructors.

Variants

EmptyRange

Buffer range length is zero.

OffsetOverflow

Buffer range offset plus length overflowed.

RangeExceedsAllocation

Buffer range exceeds the caller-supplied allocation length.

BackendMismatch

The buffer range belongs to a different backend than the descriptor requires.

Fields

expected: BackendKind

Backend required by the descriptor.

actual: BackendKind

Backend carried by the memory range.

ZeroDimension

Image or component dimensions must be nonzero.

ZeroSampling

Component sampling factors must be nonzero.

InvalidBitDepth

Bit depth must be in the supported 1..=32 range.

ZeroByteStride

Byte stride or element size must be nonzero.

LayoutExceedsBuffer

Row layout metadata exceeds the resident buffer range.

CodestreamExceedsCapacity

Codestream byte length exceeds the resident buffer capacity.

Trait Implementations

impl Clone for ResidentHandoffError

fn clone(&self) -> ResidentHandoffError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ResidentHandoffError

impl Debug for ResidentHandoffError

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

Formats the value using the given formatter.

impl Display for ResidentHandoffError

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

Formats the value using the given formatter.

impl Eq for ResidentHandoffError

impl Error for ResidentHandoffError

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 PartialEq for ResidentHandoffError

fn eq(&self, other: &ResidentHandoffError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
