Struct solana_runtime::epoch_schedule::EpochSchedule

pub struct EpochSchedule {
    pub slots_per_epoch: u64,
    pub stakers_slot_offset: u64,
    pub first_normal_epoch: u64,
    pub first_normal_slot: u64,
}

Fields

slots_per_epoch: u64

The maximum number of slots in each epoch.

stakers_slot_offset: u64

A number of slots before slot_index 0. Used to calculate finalized staked nodes.

first_normal_epoch: u64

basically: log2(slots_per_epoch) - log2(MINIMUM_SLOT_LEN)

first_normal_slot: u64

basically: 2.pow(first_normal_epoch) - MINIMUM_SLOT_LEN

Methods

impl EpochSchedule

pub fn get_slots_in_epoch(&self, epoch: u64) -> u64

get the length of the given epoch (in slots)

pub fn get_stakers_epoch(&self, slot: u64) -> u64

get the epoch for which the given slot should save off information about stakers

pub fn get_epoch_and_slot_index(&self, slot: u64) -> (u64, u64)

get epoch and offset into the epoch for the given slot

pub fn get_first_slot_in_epoch(&self, epoch: u64) -> u64
