Struct PotState

pub struct PotState { /* private fields */ }

Global PoT state.

Maintains the accurate information about PoT state and current tip.

Implementations

impl PotState

pub fn new( next_slot_input: PotNextSlotInput, parameters_change: Option<PotParametersChange>, verifier: PotVerifier, ) -> Self

Create a new PoT state

pub fn next_slot_input(&self) -> PotNextSlotInput

PoT input for the next slot

pub fn try_extend( &self, expected_existing_next_slot_input: PotNextSlotInput, best_slot: SlotNumber, best_output: PotOutput, maybe_updated_parameters_change: Option<Option<PotParametersChange>>, ) -> Result<PotNextSlotInput, PotNextSlotInput>

Extend PoT chain if it matches provided expected next slot input.

Returns Ok(new_next_slot_input) if PoT chain was extended successfully and Err(existing_next_slot_input) in case the state was changed in the meantime.

pub fn set_known_good_output( &self, slot: SlotNumber, output: PotOutput, updated_parameters_change: Option<PotParametersChange>, ) -> PotStateSetOutcome

Set known good output for time slot, overriding PoT chain if it doesn’t match the provided output.

This is typically called with information obtained from received block. It typically lags behind PoT tip and is used as a correction mechanism in case PoT reorg is needed.

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