Struct solana_libra_nextgen_crypto::bls12381::BLS12381Signature

pub struct BLS12381Signature(_);

A BLS12-381 signature

Methods

impl BLS12381Signature

pub fn to_bytes(&self) -> [u8; 96]

Serializes a BLS12381Signature

pub fn parity(&self) -> bool

Returns true if the signature contains an odd number of ones.

pub fn to_bytes(&self) -> [u8; 96]

Returns a byte string representation of the signature.

Trait Implementations

impl Signature for BLS12381Signature

type VerifyingKeyMaterial = BLS12381PublicKey

The associated verifying key type for this signature.

type SigningKeyMaterial = BLS12381PrivateKey

The associated signing key type for this signature

fn verify(
    &self,
    message: &HashValue,
    public_key: &BLS12381PublicKey
) -> Result<()>

Checks that signature is valid for message using public_key.

fn verify_arbitrary_msg(
    &self,
    message: &[u8],
    public_key: &BLS12381PublicKey
) -> Result<()>

Checks that signature is valid for an arbitrary &u8 message using public_key.

fn to_bytes(&self) -> Vec<u8>

Convert the signature into a byte representation.

fn batch_verify_signatures(
    message: &HashValue,
    keys_and_signatures: Vec<(Self::VerifyingKeyMaterial, Self)>
) -> Result<()>

The implementer can override a batch verification implementation that by default iterates over each signature. More efficient implementations exist and should be implemented for many schemes.

impl Clone for BLS12381Signature

fn clone(&self) -> BLS12381Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<BLS12381Signature> for BLS12381Signature

fn eq(&self, other: &BLS12381Signature) -> bool

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

fn ne(&self, other: &BLS12381Signature) -> bool

This method tests for !=.

impl Eq for BLS12381Signature

impl Debug for BLS12381Signature

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

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for BLS12381Signature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

type Error = CryptoMaterialError

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<BLS12381Signature, CryptoMaterialError>

Performs the conversion.

impl Serialize for BLS12381Signature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for BLS12381Signature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
