An error viewing a .npy file.

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.

Io(Error)

An error caused by I/O.

ParseHeader(ParseHeaderError)

An error parsing the file header.

InvalidData(Box<dyn Error + Send + Sync + 'static>)

Some of the data is invalid for the element type.

LengthOverflow

Overflow while computing the length of the array (in units of bytes or the number of elements) from the shape described in the file header.

WrongNdim(Option<usize>, usize)

An error caused by incorrect Dimension type.

WrongDescriptor(PyValue)

The type descriptor does not match the element type.

NonNativeEndian

The type descriptor does not match the native endianness.

MisalignedData

The start of the data is not properly aligned for the element type.

MissingBytes(usize)

The file does not contain all the data described in the header.

ExtraBytes(usize)

Extra bytes are present between the end of the data and the end of the file.

Trait Implementations

impl Debug for ViewNpyError

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

Formats the value using the given formatter.

impl Display for ViewNpyError

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

Formats the value using the given formatter.

impl Error for ViewNpyError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<ViewDataError> for ViewNpyError

fn from(err: ViewDataError) -> ViewNpyError

Performs the conversion.
