}

Failure modes of the PNG importers.

Variants

Decode(String)

The png decoder rejected the input (or an unsupported pixel format).

Empty

No frames.

SizeMismatch

Frames in a sequence disagree on size.

Fields

expected: [u32; 2]

Pixel size (width, height) of the first frame.

got: [u32; 2]

Pixel size of the frame that disagreed.

DurationsLen

durations_ms length didn’t match the frame count.

TooLarge

The slab bounding box exceeds PngImportOpts::max_dims.

Fields

dims: [u32; 3]

The would-be slab dimensions, in voxels (x, y, z).

max: [u32; 3]

The configured PngImportOpts::max_dims cap it exceeded.

Trait Implementations

impl Debug for PngImportError

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

Formats the value using the given formatter.

impl Display for PngImportError

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

Formats the value using the given formatter.

impl Error for PngImportError

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.
