Errors that can occur during encryption operations

Variants

InvalidKeySize

The provided key has the wrong byte length.

Fields

expected: usize

Expected key length in bytes.

actual: usize

Actual key length provided.

InvalidNonceSize

The nonce provided for decryption has the wrong length.

Fields

expected: usize

Expected nonce length in bytes.

actual: usize

Actual nonce length found.

KeyNotFound(String)

The requested key ID does not exist in the key store.

EncryptionFailed(String)

The AEAD encryption operation failed.

DecryptionFailed(String)

The AEAD decryption operation failed (e.g., authentication tag mismatch).

InvalidUtf8(String)

Decrypted bytes are not valid UTF-8.

InvalidFormat

The serialized encrypted-data string has an invalid format.

Base64Error(String)

Base64 decoding failed.

LockError

A read/write lock was poisoned.

HashingFailed(String)

Argon2 password hashing failed.

InvalidHash(String)

The stored password hash string is malformed.

VerificationFailed(String)

Password verification encountered an unexpected error.

Trait Implementations

impl Clone for EncryptionError

fn clone(&self) -> EncryptionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncryptionError

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

Formats the value using the given formatter.

impl Display for EncryptionError

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

Formats the value using the given formatter.

impl Error for EncryptionError

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.
