Variants

IOError(Error)

IO Error (not enough data, etc.)

WrongMagic

Wrong magic, must be “MLA”

UnsupportedVersion

Unsupported version, must be 1

InvalidECCKeyFormat

Supplied ECC key is not in the expected format

WrongBlockSubFileType

Wrong BlockSubFile magic has been encountered. Is the deserializion starting at the beginning of a block?

UTF8ConversionError(FromUtf8Error)

An error has occurred while converting into UTF8. This error could happens while parsing the block filename

FilenameTooLong

Filenames have a limited size FILENAME_MAX_SIZE

WrongArchiveWriterState

The writer state is not in the expected state for the current operation

Fields

current_state: String

expected_state: String

AssertionError(String)

Should never happens: an internal assumptions no more hold

WrongReaderState(String)

The reader state is not in the expected state for the current operation

WrongWriterState(String)

The writer state is not in the expected state for the current operation

RandError(Error)

Error with the inner random generator

PrivateKeyNeeded

A Private Key is required to decrypt the encrypted cipher key

DeserializationError

Deserialization error. May happens when starting from a wrong offset / version mismatch

SerializationError

Serialization error. May happens on I/O errors

MissingMetadata

Missing metadata (usually means the footer has not been correctly read, a repair might be needed)

BadAPIArgument(String)

Error returned on API call with incorrect argument

EndOfStream

End of stream reached, no more data should be expected

ConfigError(ConfigError)

An error happens in the configuration

DuplicateFilename

Filename already used

AuthenticatedDecryptionWrongTag

Wrong tag while decrypting authenticated data

HKDFInvalidKeyLength

Unable to expand while using the HKDF

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, f: &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
