Enum CryptoError 

#[non_exhaustive]
pub enum CryptoError {
    DecodingError(DecodeError),
    InsufficientMemory,
    NotARecipient(Fingerprint),
    NotDecrypted,
    NotSecret,
    NotType(MessageDesc),
    SerializationError(Error),
    UnauthenticCipher,
    Unknown,
}

Error type used for all fallible operations.

It is recommended to use anyhow for easy error handling or error propagation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DecodingError(DecodeError)

Base64 decoding error. See base64::DecodeError for more details.

InsufficientMemory

Insufficient memory error.

NotARecipient(Fingerprint)

Not a recipient error, see this example.

NotDecrypted

The message is not decrypted, cannot verify the signature.

NotSecret

The certificate does not contain secret keys, but it should.

NotType(MessageDesc)

The message parsing failed because the message is not of expected type.

SerializationError(Error)

Serialization error. See postcard::Error for more details.

UnauthenticCipher

AAD authentication error. This would usually indicate that the message is not authentic.

Unknown

Any other error for which there’s no logical cause to happen.

Trait Implementations

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, __formatter: &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<DecodeError> for CryptoError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<Error> for CryptoError

fn from(source: Error) -> Self

Converts to this type from the input type.
