An error reading a .npy file.

Variants

Io(Error)

An error caused by I/O.

ParseHeader(ParseHeaderError)

An error parsing the file header.

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

An error parsing the data.

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.

MissingData

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 ReadNpyError

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

Formats the value using the given formatter.

impl Display for ReadNpyError

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

Formats the value using the given formatter.

impl Error for ReadNpyError

pub 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
