batch only.Expand description
A batch verifier intended to verify a series of statements are each equivalent to zero.
Implementations§
source§impl<Id: Copy + Zeroize, G: Group + Zeroize> BatchVerifier<Id, G>where
<G as Group>::Scalar: PrimeFieldBits + Zeroize,
impl<Id: Copy + Zeroize, G: Group + Zeroize> BatchVerifier<Id, G>where <G as Group>::Scalar: PrimeFieldBits + Zeroize,
sourcepub fn new(capacity: usize) -> BatchVerifier<Id, G>
pub fn new(capacity: usize) -> BatchVerifier<Id, G>
Create a new batch verifier, expected to verify the following amount of statements.
capacity is a size hint and is not required to be accurate.
sourcepub fn queue<R: RngCore + CryptoRng, I: IntoIterator<Item = (G::Scalar, G)>>(
&mut self,
rng: &mut R,
id: Id,
pairs: I
)
pub fn queue<R: RngCore + CryptoRng, I: IntoIterator<Item = (G::Scalar, G)>>( &mut self, rng: &mut R, id: Id, pairs: I )
Queue a statement for batch verification.
sourcepub fn verify(&self) -> bool
pub fn verify(&self) -> bool
Perform batch verification, returning a boolean of if the statements equaled zero.
sourcepub fn verify_vartime(&self) -> bool
pub fn verify_vartime(&self) -> bool
Perform batch verification in variable time.
sourcepub fn blame_vartime(&self) -> Option<Id>
pub fn blame_vartime(&self) -> Option<Id>
Perform a binary search to identify which statement does not equal 0, returning None if all statements do.
This function will only return the ID of one invalid statement, even if multiple are invalid.
sourcepub fn verify_with_vartime_blame(&self) -> Result<(), Id>
pub fn verify_with_vartime_blame(&self) -> Result<(), Id>
Perform constant time batch verification, and if verification fails, identify one faulty statement in variable time.
sourcepub fn verify_vartime_with_vartime_blame(&self) -> Result<(), Id>
pub fn verify_vartime_with_vartime_blame(&self) -> Result<(), Id>
Perform variable time batch verification, and if verification fails, identify one faulty statement in variable time.
