Expand description

The type and contents of a status event emitted by a HotShot instance

This enum does not include metadata shared among all variants, such as the stage and view number, and is thus always returned wrapped in an Event.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Error

A view encountered an error and was interrupted

Fields

§error: Arc<HotShotError<TYPES>>

The underlying error

§

Decide

A new decision event was issued

Fields

§leaf_chain: Arc<LeafChain<TYPES>>

The chain of Leaves that were committed by this decision

This list is sorted in reverse view number order, with the newest (highest view number) block first in the list.

This list may be incomplete if the node is currently performing catchup. Vid Info for a decided view may be missing if this node never saw it’s share.

§qc: Arc<QuorumCertificate2<TYPES>>

The QC signing the most recent leaf in leaf_chain.

Note that the QC for each additional leaf in the chain can be obtained from the leaf before it using

§block_size: Option<u64>

Optional information of the number of transactions in the block, for logging purposes.

§

ReplicaViewTimeout

A replica task was canceled by a timeout interrupt

Fields

§view_number: TYPES::View

The view that timed out

§

ViewFinished

The view has finished. If values were decided on, a Decide event will also be emitted.

Fields

§view_number: TYPES::View

The view number that has just finished

§

ViewTimeout

The view timed out

Fields

§view_number: TYPES::View

The view that timed out

§

Transactions

New transactions were received from the network or submitted to the network by us

Fields

§transactions: Vec<TYPES::Transaction>

The list of transactions

§

DaProposal

DA proposal was received from the network or submitted to the network by us

Fields

§proposal: Proposal<TYPES, DaProposal<TYPES>>
