Error type describing faults that can happen during encryption or decryption.

This is a fairly low level type for interacting with the api directly, you probably want CryptoBoxError

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.

BadHMAC

HMAC tag verification failed

Argon2Failure

An error occurred while deriving a key from a password

Fields

source: Error

The underlying error

KeyDeserialization

Failed to deserialize a key

ItemSerialization

Failed to serialize an item

ItemDeserialization

Failed to deserialize an item

Compression

A error occurred while attempting to compress a blob

Fields

source: Error

Underlying zstd error

Decompression

A error occurred while attempting to decompress a blob

Fields

source: Error

Underlying zstd error

SegmentIO

An underlying IO error occurred while attempting to read a segment

Fields

source: Error

Underlying error

SegmentLength

A length mismatch occurred while parsing a segment

NoData

No data was provided for a segment, not even a length

NoDataIO

Suspected no data provided, please see IO error for details

Fields

source: Error

Underlying error

InvalidCompression

Invalid compression flag in serialized data

EntryIO

Failed reading/writing an entry

Fields

source: Error

Underlying error

InvalidLsmState

Indicates an invalid state where an LsmFile’s internal state points to a value that doesn’t exist

Trait Implementations

impl Debug for BackendError

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

Formats the value using the given formatter.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

where Self: Debug + Display,

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 ErrorCompat for BackendError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.
