Struct FRIFolder

source
pub struct FRIFolder<'a, F, FA, VCS>{ /* private fields */ }
Expand description

A stateful prover for the FRI fold phase.

Implementations§

source§

impl<'a, F, FA, VCS> FRIFolder<'a, F, FA, VCS>

source

pub fn new( committed_rs_code: &'a ReedSolomonCode<FA>, final_rs_code: &'a ReedSolomonCode<F>, log_batch_size: usize, committed_codeword: &'a [F], committed_codeword_vcs: &'a VCS, round_vcss: &'a [VCS], committed: &'a VCS::Committed, ) -> Result<Self, Error>

Constructs a new folder.

source

pub fn n_rounds(&self) -> usize

Number of fold rounds, including the final fold.

source

pub fn curr_round(&self) -> usize

Number of times execute_fold_round has been called.

source

pub fn execute_fold_round( &mut self, challenge: F, ) -> Result<FoldRoundOutput<VCS::Commitment>, Error>

Executes the next fold round and returns the folded codeword commitment.

As a memory efficient optimization, this method may not actually do the folding, but instead accumulate the folding challenge for processing at a later time. This saves us from storing intermediate folded codewords.

source

pub fn finalize( self, ) -> Result<(FinalMessage<F>, FRIQueryProver<'a, F, VCS>), Error>

Finalizes the FRI folding process.

This step will process any unprocessed folding challenges to produce the final folded codeword. Then it will decode this final folded codeword to get the final message. The result is the final message and a query prover instance.

This returns the final message and a query prover instance.
