Expand description

Error parsing an .npy header.

Variants§

§

MagicString

The first several bytes are not the expected magic string.

§

Version

The version number specified in the header is unsupported.

Fields

§major: u8
§minor: u8
§

HeaderLengthOverflow(u32)

The HEADER_LEN doesn’t fit in usize.

§

NonAscii

The array format string contains non-ASCII characters.

This is an error for .npy format versions 1.0 and 2.0.

§

Utf8Parse(Utf8Error)

Error parsing the array format string as UTF-8.

This does not apply to .npy format versions 1.0 and 2.0, which require the array format string to be ASCII.

§

UnknownKey(Value)

The Python dictionary in the header contains an unexpected key.

§

MissingKey(String)

The Python dictionary in the header is missing an expected key.

§

IllegalValue

The value corresponding to an expected key is illegal (e.g., the wrong type).

Fields

§key: String

The key in the header dictionary.

§value: Value

The corresponding (illegal) value.

§

DictParse(ParseError)

Error parsing the dictionary in the header.

§

MetaNotDict(Value)

The metadata in the header is not a dictionary.

§

MissingNewline

There is no newline at the end of the header.
