Enum vodozemac::olm::DecryptionError

pub enum DecryptionError {
    InvalidMAC(MacError),
    InvalidMACLength(usize, usize),
    InvalidPadding(UnpadError),
    MissingMessageKey(u64),
    TooBigMessageGap(u64, u64),
}

Error type for Olm-based decryption failures.

Variants

InvalidMAC(MacError)

The message authentication code of the message was invalid.

InvalidMACLength(usize, usize)

The length of the message authentication code of the message did not match our expected length.

InvalidPadding(UnpadError)

The ciphertext of the message isn’t padded correctly.

MissingMessageKey(u64)

The session is missing the correct message key to decrypt the message, either because it was already used up, or because the Session has been ratcheted forwards and the message key has been discarded.

TooBigMessageGap(u64, u64)

Too many messages have been skipped to attempt decrypting this message.

Trait Implementations

impl Debug for DecryptionError

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

Formats the value using the given formatter.

impl Display for DecryptionError

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

Formats the value using the given formatter.

impl Error for DecryptionError

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

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<DecryptionError> for SessionCreationError

fn from(source: DecryptionError) -> Self

impl From<MacError> for DecryptionError

fn from(source: MacError) -> Self

Converts to this type from the input type.

impl From<UnpadError> for DecryptionError

fn from(source: UnpadError) -> Self

Converts to this type from the input type.
