Enum cumulus_primitives_core::relay_chain::v8::ValidityAttestation

pub enum ValidityAttestation {
    Implicit(Signature),
    Explicit(Signature),
}

An either implicit or explicit attestation to the validity of a parachain candidate.

Variants

Implicit(Signature)

Implicit validity attestation by issuing. This corresponds to issuance of a Candidate statement.

Explicit(Signature)

An explicit attestation. This corresponds to issuance of a Valid statement.

Implementations

impl ValidityAttestation

pub fn to_compact_statement( &self, candidate_hash: CandidateHash, ) -> CompactStatement

Produce the underlying signed payload of the attestation, given the hash of the candidate, which should be known in context.

pub fn signature(&self) -> &Signature

Get a reference to the signature.

pub fn signed_payload<H>( &self, candidate_hash: CandidateHash, signing_context: &SigningContext<H>, ) -> Vec<u8>

where H: Encode,

Produce the underlying signed payload of the attestation, given the hash of the candidate, which should be known in context.

Trait Implementations

impl Clone for ValidityAttestation

fn clone(&self) -> ValidityAttestation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValidityAttestation

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

Formats the value using the given formatter.

impl Decode for ValidityAttestation

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

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 PartialEq for ValidityAttestation

fn eq(&self, other: &ValidityAttestation) -> 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 ValidityAttestation

type Identity = ValidityAttestation

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
