Variants

UnsupportedVersion(String)

The requested key block version is not supported by this implementation.

TotalBlockLengthNotMultiple

The complete key block length is not aligned to the cipher block size.

Fields

The decoded MAC does not have the required length.

Fields

expected: usize

actual: usize

MacVerificationFailed

Key block authentication failed.

Header(KeyBlockHeaderError)

Header processing failed.

Trait Implementations

impl Debug for Tr31Error

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

Formats the value using the given formatter.

impl Display for Tr31Error

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

Formats the value using the given formatter.

impl Error for Tr31Error

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
