CheckpointContentsV1

CheckpointContentsV1​

class CheckpointContentsV1

CheckpointContents are the transactions included in an upcoming checkpoint. They must have already been causally ordered. Since the causal order algorithm is the same among validators, we expect all honest validators to come up with the same order for each checkpoint content.

BCS

The BCS serialized form for this type is defined by the following ABNF:

checkpoint-contents-v1 = (vector execution-digests)      ; transaction and effect digests
(vector (vector user-signature)) ; set of user signatures for each
; transaction. MUST be the same
; length as the vector of digests

execution-digests = transaction-digest transaction-effects-digest   ; transaction, effects

init(transactionInfo:)​

convenience init(transactionInfo: [CheckpointTransactionInfo])

isEmpty()​

func isEmpty() -> Bool

Whether this checkpoint has no transactions.

len()​

func len() -> UInt64

The number of transactions in this checkpoint.

transactions()​

func transactions() -> [CheckpointTransactionInfo]
