Implementations

impl Certificate

pub fn new( value: HashedCertificateValue, round: Round, signatures: Vec<(ValidatorName, Signature)>, ) -> Self

pub fn signatures(&self) -> &Vec<(ValidatorName, Signature)>

pub fn add_signature( &mut self, signature: (ValidatorName, Signature), ) -> &Vec<(ValidatorName, Signature)>

pub fn check<'a>( &'a self, committee: &Committee, ) -> Result<&'a HashedCertificateValue, ChainError>

Verifies the certificate.

pub fn lite_certificate(&self) -> LiteCertificate<'_>

Returns the certificate without the full value.

pub fn lite_value(&self) -> LiteValue

Returns the LiteValue corresponding to the certified value.

pub fn value(&self) -> &CertificateValue

Returns the certified value.

pub fn hash(&self) -> CryptoHash

Returns the certified value’s hash.

pub fn is_signed_by(&self, validator_name: &ValidatorName) -> bool

Returns whether the validator is among the signatories of this certificate.

pub fn message_bundles_for<'a>( &'a self, medium: &'a Medium, recipient: ChainId, ) -> impl Iterator<Item = (Epoch, MessageBundle)> + 'a

Returns the bundles of messages sent via the given medium to the specified recipient. Messages originating from different transactions of the original block are kept in separate bundles. If the medium is a channel, does not verify that the recipient is actually subscribed to that channel.

pub fn requires_blob(&self, blob_id: &BlobId) -> bool
