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.

RgbaRgbImageWithAlpha

RGBA direct plans require an RGB image with explicit alpha.

RgbaFourComponentRgbCodestream

RGBA direct plans require four components in semantic R, G, B, A order.

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.

MixedCodeBlockCoding

Direct device plans do not yet represent classic and HT code-blocks in one sub-band.

Trait Implementations

impl Clone for DirectPlanUnsupportedReason

fn clone(&self) -> DirectPlanUnsupportedReason

Returns a duplicate of the value.

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

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.

impl PartialEq for DirectPlanUnsupportedReason

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

Equality operator ==.

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

Inequality operator !=.
