Struct NoCoding 

pub struct NoCoding<H> { /* private fields */ }

A trivial scheme which performs no coding at all.

Instead, each shard contains all of the data.

The commitment is simply a hash of that data. This struct is generic over the choice of commonware_cryptography::Hasher.

Trait Implementations

impl<H: Clone> Clone for NoCoding<H>

fn clone(&self) -> NoCoding<H>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<H> Debug for NoCoding<H>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<H: Hasher> Scheme for NoCoding<H>

type Commitment = <H as Hasher>::Digest

A commitment attesting to the shards of data.

type StrongShard = StrongShard

A strong shard of data, to be received by a participant.

type WeakShard = WeakShard

A weak shard shared with other participants, to aid them in reconstruction.

type CheckedShard = ()

A shard that has been checked for inclusion in the commitment.

type CheckingData = Vec<u8>

Data which can assist in checking shards.

type Error = Error

The type of errors that can occur during encoding, weakening, checking, and decoding.

fn encode( config: &Config, data: impl Buf, _strategy: &impl Strategy, ) -> Result<(Self::Commitment, Vec<Self::StrongShard>), Self::Error>

Encode a piece of data, returning a commitment, along with shards, and proofs.

fn weaken( _config: &Config, commitment: &Self::Commitment, _index: u16, shard: Self::StrongShard, ) -> Result<(Self::CheckingData, Self::CheckedShard, Self::WeakShard), Self::Error>

Take your own shard, check it, and produce a Scheme::WeakShard to forward to others.

fn check( _config: &Config, _commitment: &Self::Commitment, _checking_data: &Self::CheckingData, _index: u16, _weak_shard: Self::WeakShard, ) -> Result<Self::CheckedShard, Self::Error>

Check the integrity of a weak shard, producing a checked shard.

fn decode( _config: &Config, _commitment: &Self::Commitment, checking_data: Self::CheckingData, _shards: &[Self::CheckedShard], _strategy: &impl Strategy, ) -> Result<Vec<u8>, Self::Error>

Decode the data from shards received from other participants.
