}

Errors that can occur during symmetric encryption operations

Variants

EncryptionFailed

Encryption operation failed

DecryptionFailed

Decryption operation failed (may indicate tampering or wrong key)

InvalidKeyLength(usize)

Key has invalid length (must be 32 bytes for ChaCha20)

InvalidNonceLength(usize)

Nonce has invalid length (must be 12 bytes for ChaCha20-Poly1305)

KeyGenerationFailed

Failed to generate cryptographic key

InvalidCiphertextFormat

Ciphertext is malformed or corrupted

Trait Implementations

impl Debug for SymmetricError

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

Formats the value using the given formatter.

impl Display for SymmetricError

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

Formats the value using the given formatter.

impl Error for SymmetricError

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.
