Enum MlDsaError 

pub enum MlDsaError {
    RngFailure,
    InvalidPublicKey,
    InvalidSecretKey,
    InvalidSignature,
    ContextTooLong,
    VerificationFailed,
}

Error types for ML-DSA operations.

Each variant corresponds to a specific failure mode that can occur during key generation, signing, or verification.

Variants

RngFailure

Random number generation failed.

Returned when the underlying RNG (e.g., /dev/urandom) cannot provide bytes.

InvalidPublicKey

Invalid public key (wrong length or format).

The provided public key does not have the expected byte length for the chosen parameter set.

InvalidSecretKey

Invalid secret key (wrong length or format).

The provided secret key does not have the expected byte length for the chosen parameter set.

InvalidSignature

Invalid signature (wrong length or format).

The provided signature does not have the expected byte length for the chosen parameter set, or its internal encoding is malformed.

ContextTooLong

Context string too long (> 255 bytes).

FIPS 204 limits the optional context string to at most 255 bytes.

VerificationFailed

Signature verification failed.

Trait Implementations

impl Clone for MlDsaError

fn clone(&self) -> MlDsaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MlDsaError

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

Formats the value using the given formatter.

impl Display for MlDsaError

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

Formats the value using the given formatter.

impl Error for MlDsaError

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 MlDsaError

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