Enum DecryptError 

pub enum DecryptError {
    AuthenticationFailed,
    EmptyPassword,
    InvalidFormat(String),
    IntegrityCheckFailed,
    UnsupportedVersion(u8),
    NoMatchingKeySlot,
    CryptoError(String),
}

Encryption/decryption errors.

These errors are designed to be user-friendly and security-conscious. They never leak sensitive information like passwords or internal state.

Variants

AuthenticationFailed

Password authentication failed.

EmptyPassword

Empty password provided.

InvalidFormat(String)

Invalid archive format.

IntegrityCheckFailed

Archive integrity check failed (tampering detected).

UnsupportedVersion(u8)

Archive version not supported.

NoMatchingKeySlot

No matching key slot found.

CryptoError(String)

Internal cryptographic error.

Implementations

impl DecryptError

pub fn suggestion(&self) -> &'static str

Get a user-friendly recovery suggestion for this error.

pub fn log_message(&self) -> String

Get a sanitized error message suitable for logging.

This method ensures no sensitive information is included in logs.

Trait Implementations

impl Clone for DecryptError

fn clone(&self) -> DecryptError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecryptError

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

Formats the value using the given formatter.

impl Display for DecryptError

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

Formats the value using the given formatter.

impl Error for DecryptError

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.

impl ErrorCode for DecryptError

fn error_code(&self) -> &'static str

Get a unique error code for this error type.

impl PartialEq for DecryptError

fn eq(&self, other: &DecryptError) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
