Trait StakerRewardCalculator 

pub trait StakerRewardCalculator<Balance> {
    // Required methods
    fn calculate_validator_incentive_weight(self_stake: Balance) -> Balance;
    fn calculate_staker_reward(
        validator_total_reward: Balance,
        validator_commission: Perbill,
        validator_own_stake: Balance,
        total_exposure: Balance,
    ) -> StakerRewardResult<Balance>;
}

Handles two independent reward calculations:

1. Staker reward split (Self::calculate_staker_reward) — determines how a validator’s staking reward is divided between the validator and their nominators.

2. Validator incentive weight (Self::calculate_validator_incentive_weight) — determines a validator’s relative share of a separate validator incentive pot, based on self-stake. This incentive pot is validator-only; nominators do not receive from it.

Required Methods

fn calculate_validator_incentive_weight(self_stake: Balance) -> Balance

Compute a weight for this validator’s share of the validator incentive pot.

Called once per validator during era planning. All validators’ weights are summed, and each validator’s incentive payout is proportional to their_weight / total_weight.

fn calculate_staker_reward( validator_total_reward: Balance, validator_commission: Perbill, validator_own_stake: Balance, total_exposure: Balance, ) -> StakerRewardResult<Balance>

Split a validator’s staking reward into validator and nominator portions.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
