Enum Error 

pub enum Error {
    Authentication,
    InvalidFormat,
    BufferOverflow,
    AESCounterOverflow,
    Duplicate,
    Corrupted,
    PostcardError,
}

Errors that can occur during packet construction, serialization, or decryption.

Variants

Authentication

Cryptographic verification failed (tampered payload or invalid key).

InvalidFormat

The packet does not match the expected structure or is too small.

BufferOverflow

Postcard serialization exceeded the internal packet buffers.

AESCounterOverflow

The 5-byte AES counter exceeded its maximum value ($2^{40} - 1$).

Duplicate

Received a packet with a duplicate or older nonce (replay attack protection).

Corrupted

General payload corruption.

PostcardError

Postcard specific error during Encryption/Decryption

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 Eq for Error

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.
