Empty

whir::transcript::codecs

Struct Empty

pub struct Empty;

Expand description

An empty object. Like () with a Codec.

Trait Implementations§

impl<T> Decoding<[T]> for Empty

type Repr = [T; 0]

The output type (and length) expected by the duplex sponge. Read more

fn decode(_buf: Self::Repr) -> Self

The distribution-preserving map, that re-maps a squeezed output Decoding::Repr into a verifier message. Read more

impl<T> Encoding<[T]> for Empty

fn encode(&self) -> impl AsRef<[T]>

The function encoding prover messages into inputs to be absorbed by the duplex sponge. Read more

impl NargDeserialize for Empty

fn deserialize_from_narg(_buf: &mut &[u8]) -> VerificationResult<Self>

This map must compute the inverse of NargSerialize::serialize_into_narg, or return an error if a pre-image does not exist.
