Struct diem_sdk::types::block_info::BlockInfo

pub struct BlockInfo { /* fields omitted */ }

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: u64,
    id: HashValue,
    executed_state_id: HashValue,
    version: u64,
    timestamp_usecs: u64,
    next_epoch_state: Option<EpochState>
) -> BlockInfo

pub fn empty() -> BlockInfo

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

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 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) -> u64

pub fn timestamp_usecs(&self) -> u64

pub fn version(&self) -> u64

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
