Enum Error 

pub enum Error {
    InvalidInput(&'static str),
    InconsistentPsk,
    MissingPsk,
    UnnecessaryPsk,
    InsecurePsk,
    MessageLimitReached,
    CryptoError(CryptoError),
}

HPKE Error types.

Variants

InvalidInput(&'static str)

Generic invalid input.

InconsistentPsk

Inconsistent PSK input.

MissingPsk

PSK input is required but missing.

UnnecessaryPsk

PSK input is provided but not needed.

InsecurePsk

PSK input is too short (needs to be at least 32 bytes).

MessageLimitReached

The message limit for this AEAD, key, and nonce.

CryptoError(CryptoError)

Error passed from the underlying crypto implementation.

Implementations

impl Error

pub const fn is_invalid_input(&self) -> bool

Returns true if the error is Error::InvalidInput.

pub const fn is_unsupported_kem(&self) -> bool

Returns true if the error is due to the crypto backend not supporting the requested KEM.

Trait Implementations

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 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 From<CryptoError> for Error

fn from(e: CryptoError) -> Self

Converts to this type from the input type.
