Struct schnorr::BatchVerifier

pub struct BatchVerifier { /* fields omitted */ }

Batch signature verifier for use with Signature::verify_batched.

Methods

impl BatchVerifier

pub fn new<R: RngCore + CryptoRng>(rng: &mut R) -> Self

Returns a new instance for batch verification

pub fn with_capacity<R: RngCore + CryptoRng>(
    rng: &mut R,
    capacity: usize
) -> Self

Returns a new instance for batch verification with pre-allocated capacity n for verifying n simple schnorr signatures.

pub fn verify(self) -> Result<(), SchnorrError>

Performs the verification and returns the result.

Trait Implementations

impl BatchVerification for BatchVerifier

fn append<I, J>(
    &mut self,
    basepoint_scalar: I::Item,
    dynamic_scalars: I,
    dynamic_points: J
) where
    I: IntoIterator,
    I::Item: Borrow<Scalar>,
    J: IntoIterator<Item = Option<RistrettoPoint>>, 

Adds scalar for multiplying by a base point and pairs of dynamic scalars/points. The API admits variable-length iterators of scalars/points for compatibility with multi-key signatures (see Musig). It is responsibility of the caller to provide iterators of scalars and points with matching lengths.
