Implementations§

source§

impl PreparedBatch

source

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.

source

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

source

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

Reads a PreparedBatch from a correctly sized buffer

source

pub fn byte_len(&self) -> usize

Returns buffer size required for serialization

source

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

Serializes into exactly sized buffer
