Enum Error 

pub enum Error {
    Pem(Error),
    UnexpectedPemTag(String),
    UnexpectedAlgorithm,
    MalformedKey(String),
    TrailingData,
    InvalidSignature,
}

Available on crate feature xdsa only.

Failures of the xDSA operations.

Variants

Pem(Error)

The PEM wrapper is malformed. The inner error names the rule it broke. Raised by SecretKey::from_pem and PublicKey::from_pem.

UnexpectedPemTag(String)

The PEM block type is not the expected one, PRIVATE KEY for SecretKey::from_pem and PUBLIC KEY for PublicKey::from_pem. Carries the type found.

UnexpectedAlgorithm

The DER key names an algorithm other than composite ML-DSA-65-Ed25519-SHA512, see OID. Raised by SecretKey::from_der and PublicKey::from_der, and through them by the PEM parsers.

MalformedKey(String)

The key encoding cannot be parsed or its contents are unusable, such as invalid component keys or sizes, unexpected algorithm parameters, trailing DER bytes, or an unsupported PKCS#8 version. The message names the problem. Raised by the fallible key constructors.

TrailingData

A parsed DER key re-encodes to a different length than the input. This is a fallback consistency check in the DER constructors. The DER parser rejects appended bytes first and reports Error::MalformedKey instead, including when called through the PEM constructors.

InvalidSignature

The signature does not verify under the key for this message. Either half failing produces this, the halves are not told apart. Raised by PublicKey::verify.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
