Expand description

Variants used to categorise Error instances.

Variants§

DoesNotExist

A storage, collection or resource does not exist.

NotACollection

Referenced resource is not a collection.

NotAStorage

Referenced resource is not a storage.

AccessDenied

Access was denied by the underlying storage.

Io

Generic input / output error.

InvalidData

Storage returned invalid data.

InvalidInput

Input provided is invalid.

ReadOnly

Resources is read-only.

CollectionNotEmpty

Collection is not empty.

PreconditionFailed

A precondition has failed.

Typically, this error is returned when attempting to operate on an item using a stale Etag.

Unavailable

The requested operation is not possible on this specific instance.

Unsupported

This storage implementation does not support a required feature.

Uncategorised

Uncategorised error.

This variant is deprecated and should not be used for any new error paths.

Trait Implementations§

impl Debug for ErrorKind

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

Formats the value using the given formatter. Read more

impl Display for ErrorKind

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

Formats the value using the given formatter. Read more

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorKind

fn eq(&self, other: &ErrorKind) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
