Error type for the decoding of a SecretStorageKey.

The SecretStorageKey can be restored from a Base58 encoded string or from a string containing a passphrase.

This error type is used to report errors when trying to restore from either of those strings.

Variants

Prefix([u8; 2], [u8; 2])

The decoded secret storage key has an invalid prefix.

Parity(u8, u8)

The parity byte of the secret storage key didn’t match.

Base58(Error)

The secret storage key isn’t valid Base58.

Base64(Base64DecodeError)

The secret storage key isn’t valid Base64.

KeyLength(usize, usize)

The secret storage key is too short, we couldn’t read enough data.

Mac(MacError)

The typed in secret storage was incorrect, the MAC check failed.

MacLength(usize, usize)

The MAC of the secret storage key for the MAC check has an incorrect length.

IvLength(usize, usize)

The IV of the secret storage key for the MAC check has an incorrect length.

UnsupportedAlgorithm(String)

The secret storage key is using an unsupported secret encryption algorithm. Currently only the m.secret_storage.v1.aes-hmac-sha2 algorithm is supported.

KdfIterationCount(UInt)

The passphrase-based secret storage key has an excessively high KDF iteration count.

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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.
