Errors returned by the Metal J2K backend.

Variants

Decode(J2kError)

Error returned by the CPU or native J2K decoder.

Buffer(BufferError)

Output buffer validation failed.

UnsupportedBackend

The requested backend is unsupported by this crate.

Fields

request: BackendRequest

Backend requested by the caller.

UnsupportedMetalRequest

A Metal-specific request is structurally unsupported.

Fields

reason: &'static str

Static reason describing the rejected request.

MetalUnavailable

Metal is not available on the current host.

MetalRuntime

Metal runtime creation or device setup failed.

Fields

message: String

Runtime error message.

MetalKernel

Metal kernel launch, validation, or completion failed.

Fields

message: String

Kernel error message.

MetalStatePoisoned

Shared Metal backend state was poisoned by a prior panic.

Fields

state: &'static str

Name of the poisoned state.

Trait Implementations

impl CodecError for Error

fn is_truncated(&self) -> bool

True when the error indicates truncated input.

fn is_not_implemented(&self) -> bool

True when the error indicates an unimplemented supported surface.

fn is_unsupported(&self) -> bool

True when the error indicates unsupported input or options.

fn is_buffer_error(&self) -> bool

True when the error indicates caller buffer sizing or layout problems.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<BufferError> for Error

fn from(source: BufferError) -> Self

Converts to this type from the input type.

impl From<J2kError> for Error

fn from(source: J2kError) -> Self

Converts to this type from the input type.
