Possible cryptographic submodule error conditions.

Variants

UnsupportedVersion(u8)

Crypto primitive uses a version this library doesn't recognize (or one it no longer accepts).

OldVersion(u8)

Crypto primitive uses a version that's too old, and deemed unsafe to use.

DecryptFailed

Crypto system was unable to decrypt the contents of a Lockbox.

BadLength

The provided data for wasn't the expected length.

Fields of BadLength

step: &'static stractual: usizeexpected: usize

BadKey

A provided cryptographic key (public or private) is weak or invalid.

BadFormat(&'static str)

The data format doesn't match spec. Can occur when decoding a lockbox or attempting to decode from a String.

ObjectMismatch(&'static str)

An operation expected a specific object but didn't get it. Eg. Signature verification expects a specific version of hash and fails if it doesn't get a hash with that version, or a Lockbox should be unlocked with a specific key but we attempted to use the wrong one. This almost always indicates a logic error.

SignatureFailed

Verification of a signature failed.

NotSupportedByVault

The attempted operation isn't supported by the backing Vault.

Implementations

impl CryptoError

pub fn serde_err(&self) -> String

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

Formats the value using the given formatter.

impl Error for CryptoError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
