Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IOError(Error)

IO Error (not enough data, etc.)

WrongMagic

Wrong magic, must be “MLAFAAA”

UnsupportedVersion

Unsupported version, must be 2

InvalidKeyFormat

Supplied 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 entry data name

EntryNameTooLong

EntryNames have a limited size ENTRY_NAME_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 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 clean-truncated operation 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

DuplicateEntryName

EntryName already used

AuthenticatedDecryptionWrongTag

Wrong tag while decrypting authenticated data

HKDFInvalidKeyLength

Unable to expand while using the HKDF

HPKEError

Error during HPKE computation

InvalidLastTag

Invalid last tag

EncryptionAskedButNotMarkedPresent

User asked for encryption but archive was not marked as encrypted

WrongEndMagic

MLA archive must be terminated by EMLAAAAA

NoValidSignatureFound

SignatureVerificationAskedButNoSignatureLayerFound

MissingEndOfEncryptedInnerLayerMagic

TruncatedTag

UnknownTagPosition

Other(String)

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

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<ConfigError> for Error

fn from(error: ConfigError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(error: FromUtf8Error) -> Self

Converts to this type from the input type.
