Enum solana_libra_nextgen_crypto::traits::CryptoMaterialError

pub enum CryptoMaterialError {
    DeserializationError,
    ValidationError,
    WrongLengthError,
    CanonicalRepresentationError,
    SmallSubgroupError,
    PointNotOnCurveError,
}

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

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

DeserializationError

Key or signature material does not deserialize correctly.

ValidationError

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

WrongLengthError

Key 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.

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 PartialEq<CryptoMaterialError> for CryptoMaterialError

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

This method tests for self and other values to be equal, and is used by ==.

impl Debug for CryptoMaterialError

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

Formats the value using the given formatter.

impl Fail for CryptoMaterialError

fn name(&self) -> Option<&str>

Returns the "name" of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.
