Struct SingleSignature 

pub struct SingleSignature {
    pub signer_index: Index,
    /* private fields */
}

Single signature created by a single party who has won the lottery. Contains the underlying signature for the proof system and the registration index of the signer.

Fields

signer_index: Index

Merkle tree index of the signer.

Implementations

impl SingleSignature

pub fn verify<D: MembershipDigest>( &self, params: &Parameters, pk: &VerificationKey, stake: &Stake, avk: &AggregateVerificationKey<D>, msg: &[u8], ) -> StmResult<()>

Verify a SingleSignature by validating the underlying single signature for proof system.

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

Convert a SingleSignature into bytes

Layout

• Concatenation proof system single signature bytes:
• Length of indices
• Indices
• Sigma
• Merkle index of the signer.

pub fn from_bytes<D: MembershipDigest>( bytes: &[u8], ) -> StmResult<SingleSignature>

Extract a SingleSignature from a byte slice.

pub fn get_concatenation_signature_indices(&self) -> Vec<Index>

Get indices of the single signature for concatenation proof system.

pub fn get_concatenation_signature_sigma(&self) -> BlsSignature

Get underlying BLS signature of the concatenation single signature.

pub fn set_concatenation_signature_indices(&mut self, indices: &[Index])

Set the indices of the underlying single signature for proof system.

Trait Implementations

impl Clone for SingleSignature

fn clone(&self) -> SingleSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SingleSignature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SingleSignature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SingleSignature

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SingleSignature

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SingleSignature

fn eq(&self, other: &Self) -> 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 PartialOrd for SingleSignature

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SingleSignature

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
