Enum cumulus_primitives_core::relay_chain::v2::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, Global> 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 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 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 size_hint(&self) -> usize

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    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 MallocSizeOf for ValidityAttestation

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself. If T::size_of is a constant, consider implementing constant_size as well.

fn constant_size() -> Option<usize>where
    Self: Sized,

Used to optimize MallocSizeOf implementation for collections like Vec and HashMap to avoid iterating over them unnecessarily. The Self: Sized bound is for object safety.

impl PartialEq<ValidityAttestation> 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<MetaForm>

Returns the static type identifier for Self.
