Enum KemError 

pub enum KemError {
    EncapsulationKeyLength {
        len: usize,
    },
    EncapsulationKeyNotReduced,
    DecapsulationKeyLength {
        len: usize,
    },
    DecapsulationKeyCorrupt,
    CiphertextLength {
        len: usize,
    },
}

Why encaps or decaps refuses its inputs: the FIPS 203 §7.2–7.3 input checks.

Variants

EncapsulationKeyLength

The encapsulation key is not EK_BYTES bytes (the ek type check).

Fields

len: usize

EncapsulationKeyNotReduced

A 12-bit coefficient of the encapsulation key is q or more (the ek modulus check).

DecapsulationKeyLength

The decapsulation key is not DK_BYTES bytes (the dk type check).

Fields

len: usize

DecapsulationKeyCorrupt

The H(ek) inside the decapsulation key is not the hash of the ek beside it (the hash check).

CiphertextLength

The ciphertext is not CT_BYTES bytes (the ciphertext type check).

Fields

len: usize

Trait Implementations

impl Clone for KemError

fn clone(&self) -> KemError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KemError

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

Formats the value using the given formatter.

impl Display for KemError

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

Formats the value using the given formatter.

impl Error for KemError

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 KemError

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