Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidKeyLength,
    InvalidNonceLength,
    InvalidTagLength,
    InvalidLength,
    AadAfterPayload,
    Hardware,
}

Symmetric crypto error.

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.

InvalidKeyLength

The key length is not supported by the hardware.

InvalidNonceLength

The nonce or IV length is not valid for the cipher mode.

InvalidTagLength

The tag length is not valid for the cipher mode.

InvalidLength

The data length is not valid.

Returned when:

• the input and output lengths differ,
• a chunk that is not the last one is not a multiple of the block length, for modes that require it,
• the amount of data does not match the lengths given to AesCcm::new.

AadAfterPayload

Additional authenticated data was supplied after payload data.

Hardware

The hardware reported an error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Format for Error

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
