Fields

signature: [u8; 755]

Ring signature.

pre_outputs: BoundedVec<VrfPreOutput, ConstU32<sp_core::::bandersnatch::vrf::VrfIosVec::{constant#0}>>

VRF pre-outputs.

Implementations

impl RingVrfSignature

pub fn ring_vrf_verify( &self, data: &VrfSignData, verifier: &RingVerifier<Fp<MontBackend<FrConfig, 4>, 4>, KZG<Bls12<Config<HostHooks>>>, BandersnatchConfig<HostHooks>>, ) -> bool

Verify a ring-vrf signature.

The signature is verifiable if it has been produced by a member of the ring from which the RingVerifier has been constructed.

Trait Implementations

impl Clone for RingVrfSignature

fn clone(&self) -> RingVrfSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RingVrfSignature

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

Formats the value using the given formatter.

impl Decode for RingVrfSignature

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<RingVrfSignature, Error>

where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for RingVrfSignature

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl MaxEncodedLen for RingVrfSignature

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq for RingVrfSignature

fn eq(&self, other: &RingVrfSignature) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeInfo for RingVrfSignature

type Identity = RingVrfSignature

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
