Enum KeyError 

pub enum KeyError {
    SpkiError(Error),
    EllipticCurveError(EllipticCurveError),
    SignatureError(SignatureError),
    AeadError(AeadError),
    NonceLengthError(ReceivedExpectedError<usize, usize>),
    UnsupportedOperation,
}

Errors from key provider operations.

Deliberately does not derive Errorizable: this module builds without the derive feature, so the message strings live in exactly one place – the impl_error_display! block below.

Variants

SpkiError(Error)

SPKI encoding/decoding error

EllipticCurveError(EllipticCurveError)

Elliptic curve operation error

SignatureError(SignatureError)

Signature/ECDSA error (e.g., invalid key bytes)

AeadError(AeadError)

AEAD encryption/decryption error

NonceLengthError(ReceivedExpectedError<usize, usize>)

Nonce length mismatch

UnsupportedOperation

Operation not supported by this key provider

Trait Implementations

impl Debug for KeyError

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

Formats the value using the given formatter.

impl Display for KeyError

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

Formats the value using the given formatter.

impl Error for KeyError

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.
