Struct Bls12381Signature 

pub struct Bls12381Signature { /* private fields */ }

Available on crate feature bls only.

A BLS12-381 signature.

Implementations

impl Bls12381Signature

pub fn from_bytes(bytes: &[u8]) -> AptosResult<Self>

Creates a signature from compressed bytes (96 bytes).

Errors

Returns an error if the bytes length is not 96 bytes or if the signature deserialization fails.

pub fn from_hex(hex_str: &str) -> AptosResult<Self>

Creates a signature from a hex string.

Errors

Returns an error if hex decoding fails or if the resulting bytes are invalid.

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

Returns the signature as compressed bytes (96 bytes).

pub fn to_hex(&self) -> String

Returns the signature as a hex string.

impl Bls12381Signature

pub fn aggregate( signatures: &[&Bls12381Signature], ) -> AptosResult<Bls12381Signature>

Aggregates multiple signatures into a single aggregated signature.

The aggregated signature can be verified against an aggregated public key for the same message, or against individual public keys for different messages.

Errors

Returns an error if the list of signatures is empty or if aggregation fails.

Trait Implementations

impl Clone for Bls12381Signature

fn clone(&self) -> Bls12381Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bls12381Signature

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

Formats the value using the given formatter.

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.

impl Display for Bls12381Signature

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

Formats the value using the given formatter.

impl PartialEq for Bls12381Signature

fn eq(&self, other: &Bls12381Signature) -> 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.

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 Signature for Bls12381Signature

fn from_bytes(bytes: &[u8]) -> AptosResult<Self>

Creates a signature from compressed bytes (96 bytes).

Errors

Returns an error if the bytes length is not 96 bytes or if the signature deserialization fails.

const LENGTH: usize = BLS12381_SIGNATURE_LENGTH

The length of the signature in bytes.

type PublicKey = Bls12381PublicKey

The public key type for this signature scheme.

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

Returns the signature as bytes.

fn to_hex(&self) -> String

Returns the signature as a hex string with 0x prefix.
