h: G

Implementations

impl<G: AffineRepr> MemberCommitmentKey<G>

pub fn new<D: Digest>(label: &[u8]) -> Self

pub fn generate_using_rng<R: RngCore>(rng: &mut R) -> Self

pub fn commit(&self, member: &G::ScalarField, randomness: &G::ScalarField) -> G

Pedersen commitment to the set member, g * member + h * randomness

pub fn commit_decomposed( &self, base: u16, digits: &[G::ScalarField], randomness: &G::ScalarField, ) -> G

Given base-ary representation of a value, commit to its digits, g * (1 * digits[0] + base * digits[1] + base^2 * digits[2] + base^{n-1} * digits[n-1]) + h * randomness

pub fn commit_decomposed_given_base_powers( &self, base_powers: &[G::ScalarField], digits: &[G::ScalarField], randomness: &G::ScalarField, ) -> G

Same as commit_decomposed but takes [1, base, base^2, ..., base^{n-1}]

The general deserialize method that takes in customization flags.

fn deserialize_compressed<R>(reader: R) -> Result<Self, SerializationError>

where R: Read,

fn deserialize_compressed_unchecked<R>( reader: R, ) -> Result<Self, SerializationError>

where R: Read,

fn deserialize_uncompressed<R>(reader: R) -> Result<Self, SerializationError>

where R: Read,

where R: Read,

impl<G: AffineRepr> CanonicalSerialize for MemberCommitmentKey<G>

fn serialize_with_mode<W: Write>( &self, writer: W, compress: Compress, ) -> Result<(), SerializationError>

The general serialize method that takes in customization flags.

fn serialized_size(&self, compress: Compress) -> usize

fn serialize_compressed<W>(&self, writer: W) -> Result<(), SerializationError>

where W: Write,

fn compressed_size(&self) -> usize

fn serialize_uncompressed<W>(&self, writer: W) -> Result<(), SerializationError>

impl<G: Clone + AffineRepr> Clone for MemberCommitmentKey<G>

fn clone(&self) -> MemberCommitmentKey<G>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<G: Debug + AffineRepr> Debug for MemberCommitmentKey<G>

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

Formats the value using the given formatter.

impl<G: PartialEq + AffineRepr> PartialEq for MemberCommitmentKey<G>

fn eq(&self, other: &MemberCommitmentKey<G>) -> 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.
