Struct polkadot_node_primitives::disputes::SignedDisputeStatement

impl SignedDisputeStatement

pub fn new_unchecked_from_trusted_source(
    dispute_statement: DisputeStatement,
    candidate_hash: CandidateHash,
    session_index: SessionIndex,
    validator_public: ValidatorId,
    validator_signature: ValidatorSignature
) -> Self

Create a new SignedDisputeStatement from information that is available on-chain, and hence already can be trusted.

Attention: Not to be used other than with guaranteed fetches.

pub fn new_checked(
 dispute_statement: DisputeStatement,
 candidate_hash: CandidateHash,
 session_index: SessionIndex,
 validator_public: ValidatorId,
 validator_signature: ValidatorSignature
) -> Result<Self, ()>

Create a new SignedDisputeStatement, which is only possible by checking the signature.

pub async fn sign_explicit(
 keystore: &SyncCryptoStorePtr,
 valid: bool,
 candidate_hash: CandidateHash,
 session_index: SessionIndex,
 validator_public: ValidatorId
) -> Result<Option<Self>, KeystoreError>

Sign this statement with the given keystore and key. Pass valid = true to indicate validity of the candidate, and valid = false to indicate invalidity.

pub fn statement(&self) -> &DisputeStatement

Access the underlying dispute statement

pub fn candidate_hash(&self) -> &CandidateHash

Access the underlying candidate hash.

pub fn validator_public(&self) -> &ValidatorId

Access the underlying validator public key.

pub fn validator_signature(&self) -> &ValidatorSignature

Access the underlying validator signature.

pub fn into_validator_signature(self) -> ValidatorSignature

Consume self to return the signature.

pub fn session_index(&self) -> SessionIndex

Access the underlying session index.

pub fn from_backing_statement(
 backing_statement: &UncheckedSignedFullStatement,
 signing_context: SigningContext,
 validator_public: ValidatorId
) -> Result<Self, ()>

Convert a [SignedFullStatement] to a SignedDisputeStatement

As [SignedFullStatement] contains only the validator index and not the validator public key, the public key must be passed as well, along with the signing context.

This does signature checks again with the data provided.
