Structs

A secret witness consists of a vector $w$ of $k$ scalars

struct Witness has drop

Fields

Creates a new secret witness from a vector of scalars.

public(friend) fun new_secret_witness(w: vector<ristretto255::Scalar>): sigma_protocol_witness::Witness

Implementation

public(friend) fun new_secret_witness(w: vector<Scalar>): Witness { Witness { w } }

Returns the length of the witness: i.e., the number of scalars in it.

public(friend) fun length(self: &sigma_protocol_witness::Witness): u64

Implementation

public(friend) fun length(self: &Witness): u64 {
    self.w.length()
}

Returns the ith scalar in the witness.

public(friend) fun get(self: &sigma_protocol_witness::Witness, i: u64): &ristretto255::Scalar

Implementation

public(friend) fun get(self: &Witness, i: u64): &Scalar {
    &self.w[i]
}

Returns the underling vector of witness scalars.

public(friend) fun get_scalars(self: &sigma_protocol_witness::Witness): &vector<ristretto255::Scalar>

Implementation

public(friend) fun get_scalars(self: &Witness): &vector<Scalar> {
    &self.w
}
