Struct blockchain::epoch_info::EpochInfo

pub struct EpochInfo {
    time_frame: TimeFrame,
    epoch_leadership_schedule: Leadership,
    epoch_rewards_info: Option<EpochRewardsInfo>,
}

Fields

time_frame: TimeFrame

the time frame applicable in the current branch of the blockchain

epoch_leadership_schedule: Leadership

the leadership used to validate the current header’s leader

this object will be shared between different Ref of the same epoch

epoch_rewards_info: Option<EpochRewardsInfo>

If present, this is the rewards info distributed at the beginning of the epoch. Useful to follow up on the reward distribution history

Implementations

impl EpochInfo

pub(crate) fn new( block0: &Block, ledger: &Ledger ) -> Result<Self, EpochInfoError>

pub(crate) fn chain( &self, leadership: Leadership, epoch_rewards_info: Option<EpochRewardsInfo> ) -> Self

pub fn check_header(&self, header: &Header) -> Result<(), EpochInfoError>

pub fn epoch(&self) -> u32

pub fn slot_of(&self, date: BlockDate) -> Slot

get the slot for the given BlockDate

Having this available allows for better handling of the time scheduled of the given date.

pub fn time_of(&self, date: BlockDate) -> Option<SystemTime>

get the system time scheduled for the given block date

This function returns None if the block date is not within the time frame of this EpochInfo (i.e. the time frame has changed)

pub fn epoch_leadership_schedule(&self) -> &Leadership

pub fn epoch_rewards_info(&self) -> Option<&EpochRewardsInfo>

access the rewards info that were distributed at the end of the previous epoch (and that are accessible/visible from this epoch only).
