Enum Error 

#[non_exhaustive]
pub enum Error {
    Decode(J2kError),
    Buffer(BufferError),
    UnsupportedBackend {
        request: BackendRequest,
    },
    UnsupportedCudaRequest {
        reason: &'static str,

    CudaUnavailable,
    CudaRuntime {

    },
}

Error returned by the CUDA JPEG 2000 adapter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Decode(J2kError)

CPU JPEG 2000 decode failed.

Buffer(BufferError)

Caller-owned output buffers were invalid.

UnsupportedBackend

Backend request is unsupported by this adapter.

Fields

request: BackendRequest

Requested backend.

UnsupportedCudaRequest

CUDA request is unsupported by the strict CUDA adapter contract.

Fields

reason: &'static str

Human-readable rejection reason.

CudaUnavailable

CUDA runtime or device is unavailable.

CudaRuntime

CUDA runtime returned an error.

Fields

message: String

Runtime error message.

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.
