The various errors that can be returned during the decryption process.

Variants

ArmoredWhenSeeking

Seeking was attempted on an ASCII-armored encrypted message, which is unsupported.

DecryptionFailed

The message failed to decrypt.

ExcessiveWork

The message used an excessive work factor for passphrase encryption.

Fields of ExcessiveWork

required: u8

The work factor required to decrypt.

target: u8

The target work factor for this device (around 1 second of work).

InvalidMac

The MAC in the message header was invalid.

Io(Error)

An I/O error occurred during decryption.

KeyDecryptionFailed

Failed to decrypt an encrypted key.

MessageRequiresKeys

The provided message requires keys to decrypt.

MessageRequiresPassphrase

The provided message requires a passphrase to decrypt.

NoMatchingKeys

None of the provided keys could be used to decrypt the message.

UnknownFormat

An unknown age format, probably from a newer version.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

fn from(_: Error) -> Self

Performs the conversion.

impl From<Error> for Error

fn from(e: Error) -> Self

Performs the conversion.

impl From<MacError> for Error

fn from(_: MacError) -> Self

Performs the conversion.
