Fields

epoch: EpochId

sequence_number: CheckpointSequenceNumber

network_total_transactions: u64

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

content_digest: CheckpointContentsDigest

previous_digest: Option<CheckpointDigest>

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

checkpoint_commitments: Vec<CheckpointCommitment>

Commitments to checkpoint-specific state (e.g. txns in checkpoint, objects read/written in checkpoint).

end_of_epoch_data: Option<EndOfEpochData>

Present only on the final checkpoint of the epoch.

version_specific_data: Vec<u8>

CheckpointSummary is not an evolvable structure - it must be readable by any version of the code. Therefore, in order to allow extensions to be added to CheckpointSummary, we allow opaque data to be added to checkpoints which can be deserialized based on the current protocol version.

Implementations

impl CheckpointSummary

pub fn digest(&self) -> CheckpointDigest

Available on crate features hash and serde only.

Trait Implementations

impl Arbitrary for CheckpointSummary

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<CheckpointSummary>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(args: <Self as Arbitrary>::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for CheckpointSummary

fn clone(&self) -> CheckpointSummary

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointSummary

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CheckpointSummary

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CheckpointSummary

fn eq(&self, other: &CheckpointSummary) -> 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 CheckpointSummary

Available on crate feature serde only.

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 CheckpointSummary

impl StructuralPartialEq for CheckpointSummary
