Enum MlKemError 

pub enum MlKemError {
    RngFailure,
    InvalidEncapsulationKey,
    InvalidDecapsulationKey,
    InvalidCiphertext,
}

Errors returned by ML-KEM operations.

All error variants are designed to avoid leaking secret information; timing is independent of the specific failure path.

Variants

RngFailure

The cryptographic random number generator failed to produce bytes.

This typically indicates a system-level failure (e.g., /dev/urandom is unavailable).

InvalidEncapsulationKey

The provided encapsulation (public) key has an invalid length or fails the modulus check required by FIPS 203 Section 7.2.

InvalidDecapsulationKey

The provided decapsulation (private) key has an invalid length or fails the H(ek) integrity check embedded in the key.

This may indicate storage corruption or fault injection.

InvalidCiphertext

The provided ciphertext has an invalid length for the parameter set.

Trait Implementations

impl Clone for MlKemError

fn clone(&self) -> MlKemError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MlKemError

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

Formats the value using the given formatter.

impl Display for MlKemError

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

Formats the value using the given formatter.

impl Error for MlKemError

Available on crate feature std only.

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 PartialEq for MlKemError

fn eq(&self, other: &MlKemError) -> 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.
