Implementations

impl PohRecorder

pub fn would_be_leader(&self, within_next_n_ticks: u64) -> bool

pub fn leader_after_n_slots(&self, slots: u64) -> Option<Pubkey>

pub fn next_slot_leader(&self) -> Option<Pubkey>

pub fn bank(&self) -> Option<Arc<Bank>>

pub fn has_bank(&self) -> bool

pub fn tick_height(&self) -> u64

pub fn ticks_per_slot(&self) -> u64

pub fn reached_leader_slot(&self) -> (bool, u64, Slot, Slot)

returns if leader slot has been reached, how many grace ticks were afforded, imputed leader_slot and self.start_slot reached_leader_slot() == true means “ready for a bank”

) -> (Self, Receiver<WorkingBankEntry>)

A recorder to synchronize PoH with the following data structures

• bank - the LastId’s queue is updated on tick and record events
• sender - the Entry channel that outputs to the ledger
