Expand description

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.

RecordNotFound

Record not found

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: IOErrorKind

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(IOErrorKind)

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
