Struct diem_types::block_info::BlockInfo

pub struct BlockInfo { /* private fields */ }

This structure contains all the information needed for tracking a block without having access to the block or its execution output state. It assumes that the block is the last block executed within the ledger.

Implementations

impl BlockInfo

pub fn new( epoch: u64, round: Round, id: HashValue, executed_state_id: HashValue, version: Version, timestamp_usecs: u64, next_epoch_state: Option<EpochState> ) -> Self

pub fn empty() -> Self

pub fn random(round: Round) -> Self

pub fn genesis( genesis_state_root_hash: HashValue, validator_set: ValidatorSet ) -> Self

Create a new genesis block. The genesis block is effectively the blockchain state after executing the initial genesis transaction.

• genesis_state_root_hash - the state tree root hash after executing the initial genesis transaction.

• validator_set - the initial validator set, configured when generating the genesis transaction itself and emitted after executing the genesis transaction. Using this genesis block means transitioning to a new epoch (GENESIS_EPOCH + 1) with this validator_set.

pub fn mock_genesis(validator_set: Option<ValidatorSet>) -> Self

Create a mock genesis BlockInfo with an empty state tree and empty validator set.

pub fn next_block_epoch(&self) -> u64

The epoch after this block committed

pub fn epoch(&self) -> u64

pub fn executed_state_id(&self) -> HashValue

pub fn has_reconfiguration(&self) -> bool

pub fn id(&self) -> HashValue

pub fn next_epoch_state(&self) -> Option<&EpochState>

pub fn round(&self) -> Round

pub fn timestamp_usecs(&self) -> u64

pub fn version(&self) -> Version

pub fn match_ordered_only(&self, block_info: &BlockInfo) -> bool

This function checks if the current BlockInfo has exactly the same values in those fields that will not change after execution, compred to a given BlockInfo

pub fn is_ordered_only(&self) -> bool

This function checks if the current BlockInfo is consistent with the dummy values we put in the ordering state computer and it is not empty

Trait Implementations

impl Arbitrary for BlockInfo

type Parameters = (<u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters, <HashValue as Arbitrary>::Parameters, <HashValue as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters, <Option<EpochState> as Arbitrary>::Parameters)

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

type Strategy = Map<(<u64 as Arbitrary>::Strategy, <u64 as Arbitrary>::Strategy, <HashValue as Arbitrary>::Strategy, <HashValue as Arbitrary>::Strategy, <u64 as Arbitrary>::Strategy, <u64 as Arbitrary>::Strategy, <Option<EpochState> as Arbitrary>::Strategy), fn(_: (u64, u64, HashValue, HashValue, u64, u64, Option<EpochState>)) -> BlockInfo>

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

fn arbitrary_with(_top: Self::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 BlockInfo

fn clone(&self) -> BlockInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlockInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BlockInfo

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

Formats the value using the given formatter.

impl PartialEq<BlockInfo> for BlockInfo

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for BlockInfo

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

Serialize this value into the given Serde serializer.
