A list specifying categories of Storage error.

Variants

ActiveBlobNotSet

Active blob not set, often initialization failed.

WrongConfig

Input configuration is wrong.

Uninitialized

Probably storage initialization failed.

WorkDirInUse

Work directory is locked by another storage. Or the operation lacked the necessary privileges to complete. Stop another storage or delete *.lock file

WorkDirUnavailable

Fields

path: PathBuf

path of unavailable dir

msg: String

os error message (or custom one if we can’t create directory during initialization)

io_err_kind: ErrorKind

IO Error Kind (NotFound or Other)

Happens when try to write/read from work dir that doesn’t exist. In case when work dir wasn’t created or disk was unmounted. Contains path to failed work dir, IOError description and IOErrorKind.

FileUnavailable(ErrorKind)

Blob detects os errors during IO operation which indicate possible problems with disk

KeySizeMismatch

Storage was initialized with different key size

ActiveBlobDoesntExist

Active blob doesn’t exist

ActiveBlobExists

Active blob already exists

RecordExists

Record with the same key and the same metadata already exists

EmptyIndexBunch

Any error not part of this list

Index(String)

Index error

Bincode(String)

Bincode serialization deserialization error

IO(String)

std::io::Error

WrongFileNamePattern(PathBuf)

Wrong file name pattern in config

Conversion(String)

Conversion error

Validation

Fields

kind: ValidationErrorKind

Describes what check failed.

cause: String

Description of an error cause.

Validation errors, eg. magic byte check

Other

Other error

Trait Implementations

impl Clone for Kind

fn clone(&self) -> Kind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Kind

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

Formats the value using the given formatter.

impl From<Kind> for Error

fn from(kind: Kind) -> Self

Converts to this type from the input type.

impl PartialEq<Kind> for Kind

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

This method tests for self and other values to be equal, and is used by ==.

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

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