Enum RuneError 

pub enum RuneError {
    RingTooSmall,
    SignerIndexOutOfRange,
    InconsistentRingParameter,
    MalformedSignature,
    MalformedChallenge,
    MalformedPublicKey,
    RejectionSamplingFailed,
}

Errors returned by Rune key, signing, and verification operations.

Variants

RingTooSmall

Ring size is less than 2.

SignerIndexOutOfRange

Signer index is out of range for the given ring.

InconsistentRingParameter

Not all public keys in the ring share the same public matrix seed.

MalformedSignature

A signature field has wrong length or structure.

MalformedChallenge

A supplied challenge polynomial has invalid weight or coefficients.

MalformedPublicKey

A public key has invalid structure.

RejectionSamplingFailed

Rejection sampling did not terminate within the maximum number of attempts.

Trait Implementations

impl Clone for RuneError

fn clone(&self) -> RuneError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuneError

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

Formats the value using the given formatter.

impl Display for RuneError

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

Formats the value using the given formatter.

impl Eq for RuneError

impl Error for RuneError

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 RuneError

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