Expand description

Common data types and abstractions for the consensus engine.

Structs§

CommitCertificate: Represents a certificate containing the message (height, round, value_id) and the commit signatures.
CommitSignature: Represents a signature for a commit certificate, with the address of the validator that produced it.
EnterRoundCertificate: Represents a local certificate that triggered or will trigger the start of a new round.
PolkaCertificate: Represents a certificate witnessing a Polka at a given height and round.
PolkaSignature: Represents a signature for a polka certificate, with the address of the validator that produced it.
RoundCertificate: Represents a certificate used to justify entering a new round at a given height.
RoundSignature: Represents a signature for a round certificate, with the address of the validator that produced it.
SignedMessage: A signed message, ie. a message emitted by a validator and signed by its private key.
ThresholdParam: Represents the different quorum thresholds.
ThresholdParams: Represents the different quorum thresholds.
Timeout: A timeout for a round step.
ValueResponse: Represents a response to a value request.
VoteExtensions: A set of vote extensions.

CertificateError: Represents an error that can occur when verifying a certificate.
NilOrVal: Represents either Nil or a value of type Value.
Round: A round number.
RoundCertificateType: Describes the type of a RoundCertificate.
Threshold: Represents the different quorum thresholds.
TimeoutKind: The timeout type. There may be multiple timeouts running in a given step.
Validity: Whether or not a proposal is valid.
ValueOrigin: Protocols that diseminate Value
ValuePayload: The possible messages used to deliver proposals
VoteType: A type of vote.

Address: Defines the requirements for an address.
Context: This trait allows to abstract over the various datatypes that are used in the consensus engine.
Extension: Vote extensions allows applications to extend the pre-commit vote with arbitrary data. This allows applications to force their validators to do more than just validate blocks within consensus.
Height: Defines the requirements for a height type.
Proposal: Defines the requirements for a proposal type.
ProposalPart: Defines the requirements for a proposal part type.
SigningProvider: A provider of signing functionality for the consensus engine.
SigningProviderExt: Extension trait providing additional certificate verification functionality for signing providers.
SigningScheme: A signing scheme that can be used to sign votes and verify such signatures.
Validator: Defines the requirements for a validator.
ValidatorSet: Defines the requirements for a validator set.
Value: The Value type denotes the value v carried by the Proposal consensus message broadcast by the proposer of a round of consensus.
Vote: Defines the requirements for a vote.
