Variants

Io(Error)

I/O error from the underlying storage backend.

Serialization(String)

Footer serialization or deserialization failed.

InvalidFooter(String)

The file footer is invalid or corrupt.

ArrayNotFound

The requested array was not found.

Fields

name: String

Name of the array that was not found.

BlockOutOfRange

A referenced block id is out of range.

Fields

block_id: u32

The invalid block id.

Codec(String)

Compression or decompression failed.

Storage(String)

Storage backend error.

ArrayAlreadyExists

The array already exists.

Fields

name: String

Name of the duplicate array.

DTypeMismatch

The dtype of the data does not match the dtype of the array.

Fields

expected: DType

The dtype declared in the array metadata.

actual: DType

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.
