Enum CryptoError 

pub enum CryptoError {
    UnsupportedAlgorithm(&'static str),
    InvalidKeyLength,
    CipherError,
    RandomSource,
}

Error type for cryptographic provider operations.

This covers failures that originate from the crypto backend itself: unsupported algorithms, invalid key material, and cipher-level errors. Protocol-level framing errors (e.g., wrong privParameters length) live in PrivacyError.

Variants

UnsupportedAlgorithm(&'static str)

The crypto backend does not support the requested algorithm.

For example, the FIPS provider does not support MD5 or DES.

InvalidKeyLength

The key length is invalid for the requested operation.

CipherError

The cipher operation failed internally.

RandomSource

The OS random source is unavailable.

Trait Implementations

impl Clone for CryptoError

fn clone(&self) -> CryptoError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CryptoError

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

Formats the value using the given formatter.

impl Display for CryptoError

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

Formats the value using the given formatter.

impl Error for CryptoError

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<CryptoError> for PrivacyError

fn from(e: CryptoError) -> Self

Converts to this type from the input type.

impl PartialEq for CryptoError

fn eq(&self, other: &CryptoError) -> 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.
