Enum CryptoMaterialError

pub enum CryptoMaterialError {
    SerializationError,
    DeserializationError,
    ValidationError,
    WrongLengthError,
    CanonicalRepresentationError,
    SmallSubgroupError,
    PointNotOnCurveError,
    BitVecError(String),
    AggregateError,
}

An error type for key and signature validation issues, see ValidCryptoMaterial.

This enum reflects there are two interesting causes of validation failure for the ingestion of key or signature material: deserialization errors (often, due to mangled material or curve equation failure for ECC) and validation errors (material recognizable but unacceptable for use, e.g. unsafe).

Variants

SerializationError

Struct to be signed does not serialize correctly.

DeserializationError

Key or signature material does not deserialize correctly.

ValidationError

Key or signature material deserializes, but is otherwise not valid.

WrongLengthError

Key, threshold or signature material does not have the expected size.

CanonicalRepresentationError

Part of the signature or key is not canonical resulting to malleability issues.

SmallSubgroupError

A curve point (i.e., a public key) lies on a small group.

PointNotOnCurveError

A curve point (i.e., a public key) does not satisfy the curve equation.

BitVecError(String)

BitVec errors in accountable multi-sig schemes.

AggregateError

bls aggerate error

Trait Implementations

impl Clone for CryptoMaterialError

fn clone(&self) -> CryptoMaterialError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CryptoMaterialError

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

Formats the value using the given formatter.

impl Display for CryptoMaterialError

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

Formats the value using the given formatter.

impl Error for CryptoMaterialError

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 CryptoMaterialError

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