Enum CipherError 

#[non_exhaustive]
pub enum CipherError {
    KeyDecode(String),
    KeyWrongLength(usize),
    Encrypt(String),
    CiphertextDecode(String),
    CiphertextTruncated,
    NonceSize,
    Decrypt(String),
    PlaintextUtf8(String),
}

Errors produced by TokenCipher.

Every variant is “unrecoverable for this session” from the consumer’s point of view — the correct response is to drop the cached auth context and force the user to re-auth. There is no retry that will turn a cipher failure into success.

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.

KeyDecode(String)

KeyWrongLength(usize)

Encrypt(String)

CiphertextDecode(String)

CiphertextTruncated

NonceSize

Decrypt(String)

PlaintextUtf8(String)

Trait Implementations

impl Debug for CipherError

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

Formats the value using the given formatter.

impl Display for CipherError

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

Formats the value using the given formatter.

impl Error for CipherError

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.
