Implementations

impl PreparedBatch

pub fn new<T, I, R>( transcripts: I, signatures: &[Signature], public_keys: &[PublicKey] ) -> PreparedBatch

where T: SigningTranscript, I: IntoIterator<Item = T>,

Create a half-aggregated aka prepared batch signature from many other signatures.

pub fn verify<T, I>( &self, transcripts: I, public_keys: &[PublicKey], deduplicate_public_keys: bool ) -> SignatureResult<()>

where T: SigningTranscript, I: IntoIterator<Item = T>,

Verify a half-aggregated aka prepared batch signature

pub fn read_bytes(&self, bytes: &[u8]) -> SignatureResult<PreparedBatch>

Reads a PreparedBatch from a correctly sized buffer

pub fn byte_len(&self) -> usize

Returns buffer size required for serialization

pub fn write_bytes(&self, bytes: &mut [u8])

Serializes into exactly sized buffer
