Structured reasons why a direct JPEG 2000 device plan cannot be built.

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.

GrayscaleImageWithoutAlpha

Grayscale direct plans require grayscale images without alpha.

GrayscaleSingleTileCodestream

Grayscale direct plans require a single-tile codestream.

GrayscaleSingleComponentCodestream

Grayscale direct plans require a single-component codestream.

ColorRgbImageWithoutAlpha

Color direct plans require RGB images without alpha.

ColorSingleTileCodestream

Color direct plans require a single-tile codestream.

ColorThreeComponentRgbCodestream

Color direct plans require three RGB components.

ComponentIndexOutOfRange

A direct component plan index did not exist.

ComponentUnitSampled

Direct component plans require unit-sampled components.

ComponentDecompositionIndexOutOfRange

A direct component decomposition index did not exist.

impl Eq for DirectPlanUnsupportedReason

impl Error for DirectPlanUnsupportedReason

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.
