Enum CodecError 

pub enum CodecError {
    InsufficientCapacity {
        image: (usize, usize),
        tensor: (usize, usize),
    },
    UnsupportedDtype(DType),
    UnsupportedFormat(PixelFormat),
    Unsupported(UnsupportedFeature),
    InvalidData(String),
    Io(Error),
    Tensor(Error),
}

Errors that can occur during image decoding.

Variants

InsufficientCapacity

Image dimensions exceed the tensor’s capacity.

Fields

image: (usize, usize)

(width, height) of the decoded image.

tensor: (usize, usize)

(width, height) capacity of the destination tensor.

UnsupportedDtype(DType)

The tensor’s element type is not supported for image decoding.

UnsupportedFormat(PixelFormat)

The requested pixel format is not supported for this image type.

Unsupported(UnsupportedFeature)

The image data is well-formed but uses a feature this decoder does not implement. Callers can pattern-match on the carried UnsupportedFeature to react programmatically (e.g. transcode before retry, surface a precise message, or skip gracefully).

InvalidData(String)

The image data is corrupted, truncated, or not a recognized format.

Io(Error)

I/O error reading image data.

Tensor(Error)

An error from the tensor subsystem.

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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<Error> for CodecError

fn from(e: Error) -> Self

impl From<Error> for CodecError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<PngDecodeErrors> for CodecError

fn from(e: PngDecodeErrors) -> Self
