Fields

epoch: EpochId

Checkpoint’s epoch ID

sequence_number: CheckpointSequenceNumber

Checkpoint sequence number

digest: CheckpointDigest

Checkpoint digest

network_total_transactions: u64

Total number of transactions committed since genesis, including those in this checkpoint.

previous_digest: Option<CheckpointDigest>

Digest of the previous checkpoint

epoch_rolling_gas_cost_summary: GasCostSummary

The running total gas costs of all transactions included in the current epoch so far until this checkpoint.

timestamp_ms: CheckpointTimestamp

Timestamp of the checkpoint - number of milliseconds from the Unix epoch Checkpoint timestamps are monotonic, but not strongly monotonic - subsequent checkpoints can have same timestamp if they originate from the same underlining consensus commit

end_of_epoch_data: Option<EndOfEpochData>

Present only on the final checkpoint of the epoch.

transactions: Vec<TransactionDigest>

Transaction digests

checkpoint_commitments: Vec<CheckpointCommitment>

Commitments to checkpoint state

validator_signature: AggregateAuthoritySignature

Validator Signature

Trait Implementations

impl Clone for Checkpoint

fn clone(&self) -> Checkpoint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Checkpoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Checkpoint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<(CheckpointSummary, CheckpointContents, BLS12381AggregateSignature)> for Checkpoint

fn from( (summary, contents, signature): (CheckpointSummary, CheckpointContents, AggregateAuthoritySignature), ) -> Self

Converts to this type from the input type.

impl JsonSchema for Checkpoint

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for Checkpoint

fn eq(&self, other: &Checkpoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Checkpoint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Checkpoint

impl StructuralPartialEq for Checkpoint
