pub struct SignedDisputeStatement { /* private fields */ }
Expand description
A checked dispute statement from an associated validator.
Implementations§
source§impl SignedDisputeStatement
impl SignedDisputeStatement
sourcepub fn new_unchecked_from_trusted_source(
dispute_statement: DisputeStatement,
candidate_hash: CandidateHash,
session_index: SessionIndex,
validator_public: ValidatorId,
validator_signature: ValidatorSignature,
) -> Self
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.
sourcepub fn new_checked(
dispute_statement: DisputeStatement,
candidate_hash: CandidateHash,
session_index: SessionIndex,
validator_public: ValidatorId,
validator_signature: ValidatorSignature,
) -> Result<Self, ()>
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.
sourcepub fn sign_explicit(
keystore: &KeystorePtr,
valid: bool,
candidate_hash: CandidateHash,
session_index: SessionIndex,
validator_public: ValidatorId,
) -> Result<Option<Self>, SignedDisputeStatementError>
pub fn sign_explicit( keystore: &KeystorePtr, valid: bool, candidate_hash: CandidateHash, session_index: SessionIndex, validator_public: ValidatorId, ) -> Result<Option<Self>, SignedDisputeStatementError>
Sign this statement with the given keystore and key. Pass valid = true
to
indicate validity of the candidate, and valid = false
to indicate invalidity.
sourcepub fn candidate_hash(&self) -> &CandidateHash
pub fn candidate_hash(&self) -> &CandidateHash
Access the underlying candidate hash.
sourcepub fn validator_public(&self) -> &ValidatorId
pub fn validator_public(&self) -> &ValidatorId
Access the underlying validator public key.
sourcepub fn validator_signature(&self) -> &ValidatorSignature
pub fn validator_signature(&self) -> &ValidatorSignature
Access the underlying validator signature.
sourcepub fn into_validator_signature(self) -> ValidatorSignature
pub fn into_validator_signature(self) -> ValidatorSignature
Consume self to return the signature.
sourcepub fn session_index(&self) -> SessionIndex
pub fn session_index(&self) -> SessionIndex
Access the underlying session index.
sourcepub fn from_backing_statement<T>(
backing_statement: &UncheckedSigned<T, CompactStatement>,
signing_context: SigningContext,
validator_public: ValidatorId,
) -> Result<Self, ()>
pub fn from_backing_statement<T>( backing_statement: &UncheckedSigned<T, CompactStatement>, signing_context: SigningContext, validator_public: ValidatorId, ) -> Result<Self, ()>
Convert a unchecked backing statement to a SignedDisputeStatement
As the unchecked backing statement 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.
