Struct solana_stake_program::stake_state::Stake

pub struct Stake {
    pub delegation: Delegation,
    pub credits_observed: u64,
}

Fields

delegation: Delegation

credits_observed: u64

credits observed is credits from vote account state when delegated or redeemed

    history: Option<&StakeHistory>,
    fix_stake_deactivate: bool
) -> u64

    &mut self,
    point_value: &PointValue,
    vote_state: &VoteState,
    stake_history: Option<&StakeHistory>,
    inflation_point_calc_tracer: &mut Option<impl FnMut(&InflationPointCalculationEvent)>,
    fix_stake_deactivate: bool
) -> Option<(u64, u64)>

    &self,
    vote_state: &VoteState,
    stake_history: Option<&StakeHistory>,
    inflation_point_calc_tracer: &mut Option<impl FnMut(&InflationPointCalculationEvent)>,
    fix_stake_deactivate: bool
) -> u128

pub fn calculate_rewards(
    &self,
    point_value: &PointValue,
    vote_state: &VoteState,
    stake_history: Option<&StakeHistory>,
    inflation_point_calc_tracer: &mut Option<impl FnMut(&InflationPointCalculationEvent)>,
    fix_stake_deactivate: bool
) -> Option<(u64, u64, u64)>

for a given stake and vote_state, calculate what distributions and what updates should be made returns a tuple in the case of a payout of:

• staker_rewards to be distributed
• voter_rewards to be distributed
• new value for credits_observed in the stake returns None if there’s no payout or if any deserved payout is < 1 lamport
