Enum DecryptError 

#[non_exhaustive]
pub enum DecryptError {
    CiphertextTooShort {
        len: usize,
    },
    Open,
}

Why decrypt could not open a ciphertext.

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.

CiphertextTooShort

The ciphertext is shorter than the nonce it must start with.

Fields

len: usize

The length of the ciphertext, in bytes.

Open

The ciphertext could not be opened: it does not authenticate under the key (the key is wrong or the ciphertext was altered), it is too short to hold the tag, or it is longer than the cipher can process as one message.

Trait Implementations

impl Debug for DecryptError

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

Formats the value using the given formatter.

impl Display for DecryptError

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

Formats the value using the given formatter.

impl Error for DecryptError

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<DecryptError> for EncryptedReadError

fn from(source: DecryptError) -> Self

Converts to this type from the input type.
