Struct sigma_fun::All

pub struct All<S, N> { /* private fields */ }

Available on crate feature alloc only.

Combinator for proving all of N statements of the same type is true.

Implementations

impl<S, N> All<S, N>

pub fn new(sigma: S) -> Self

Create a All<N,S> protocol from a Sigma protocol S.

Trait Implementations

impl<S: Clone, N: Clone> Clone for All<S, N>

fn clone(&self) -> All<S, N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug, N: Debug> Debug for All<S, N>

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

Formats the value using the given formatter.

impl<S: Default, N: Default> Default for All<S, N>

fn default() -> All<S, N>

Returns the “default value” for a type.

impl<S, N> Display for All<S, N>

where All<S, N>: Sigma,

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

Formats the value using the given formatter.

impl<S: PartialEq, N: PartialEq> PartialEq for All<S, N>

fn eq(&self, other: &All<S, N>) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<N: Unsigned, S: Sigma> Sigma for All<S, N>

type Witness = Vec<<S as Sigma>::Witness>

The witness for the relation.

type Statement = Vec<<S as Sigma>::Statement>

The elements of the statement the prover is proving.

type AnnounceSecret = Vec<<S as Sigma>::AnnounceSecret>

The type for the secret the prover creates when generating the proof.

type Announcement = Vec<<S as Sigma>::Announcement>

The type for the public announcement the prover sends in the first round of the protocol.

type Response = Vec<<S as Sigma>::Response>

The type for the response the prover sends in the last round of the protocol.

type ChallengeLength = <S as Sigma>::ChallengeLength

The length as a typenum

fn respond( &self, witness: &Self::Witness, statement: &Self::Statement, announce_secret: Self::AnnounceSecret, announce: &Self::Announcement, challenge: &GenericArray<u8, Self::ChallengeLength> ) -> Self::Response

Generates the prover’s response for the verifier’s challenge.

fn announce( &self, statement: &Self::Statement, announce_secret: &Self::AnnounceSecret ) -> Self::Announcement

Generates the prover’s announcement message.

fn gen_announce_secret<Rng: CryptoRng + RngCore>( &self, witness: &Self::Witness, rng: &mut Rng ) -> Self::AnnounceSecret

Generates the secret data to create the announcement

fn sample_response<Rng: CryptoRng + RngCore>( &self, rng: &mut Rng ) -> Self::Response

Uniformly samples a response from the response space of the Sigma protocol.

fn implied_announcement( &self, statement: &Self::Statement, challenge: &GenericArray<u8, Self::ChallengeLength>, response: &Self::Response ) -> Option<Self::Announcement>

Computes what the announcement must be for the response to be valid.

fn hash_statement<H: Update>(&self, hash: &mut H, statements: &Self::Statement)

Hashes the statement.

fn hash_announcement<H: Update>( &self, hash: &mut H, announcements: &Self::Announcement )

Hashes the announcement.

fn hash_witness<H: Update>(&self, hash: &mut H, witnesses: &Self::Witness)

Hashes the witness.

impl<S: Writable, N: Unsigned> Writable for All<S, N>

fn write_to<W: Write>(&self, w: &mut W) -> Result

Asks the thing to write itself to W.
