Enum Error 

pub enum Error {
    InvalidKeyLen,
    InvalidIvLen,
    InvalidPaddingForMode,
    OutputBufferTooSmall {
        needed: usize,
    },
    NotInitialized,
    AlreadyFinalized,
    UnpaddedInput,
    BadPadding,
}

Errors returned by Cipher.

Variants

InvalidKeyLen

The supplied key length does not match the algorithm.

InvalidIvLen

The supplied IV length does not match the mode’s block size.

InvalidPaddingForMode

Padding::None is required for stream-shaped modes (CTR), and padded modes are required for block-shaped modes (ECB, CBC) if the caller wants to feed unaligned data.

OutputBufferTooSmall

Caller-provided output buffer is too small for the bytes that the call would have produced. The needed field reports the total number of bytes the call would have written.

Fields

needed: usize

The total number of output bytes the call would have written.

NotInitialized

update / finalize was called before Cipher::init.

AlreadyFinalized

update / init was called after Cipher::finalize without re-initializing.

UnpaddedInput

Encrypting or decrypting with Padding::None but the total input was not a multiple of the block size.

BadPadding

Decrypted padding bytes do not match the declared padding scheme.

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 Debug for Error

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

Formats the value using the given formatter.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error

impl Eq for Error
