Enum double_ratchet::DecryptError

pub enum DecryptError {
    DecryptFailure,
    MessageKeyNotFound,
    SkipTooLarge,
    StorageFull,
}

Error that may occur during ratchet_decrypt

Variants

DecryptFailure

Could not verify-decrypt the ciphertext + associated data + header

MessageKeyNotFound

Could not find the message key required for decryption

Note that this implementation is not always able to detect when a MessageKey can't be found: a DecryptFailure may be triggered instead.

SkipTooLarge

Header message counter is too large

StorageFull

Storage of skipped message keys is full

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for DecryptError

fn clone(&self) -> DecryptError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for DecryptError

impl Display for DecryptError

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

Formats the value using the given formatter.

impl Debug for DecryptError

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

Formats the value using the given formatter.

impl Error for DecryptError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

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

The lower-level source of this error, if any.
