Implementations

impl RentCollector

pub fn new(
    epoch: Epoch,
    epoch_schedule: &EpochSchedule,
    slots_per_year: f64,
    rent: &Rent
) -> Self

pub fn clone_with_epoch(&self, epoch: Epoch) -> Self

pub fn should_collect_rent(
    &self,
    address: &Pubkey,
    account: &impl ReadableAccount,
    rent_for_sysvars: bool
) -> bool

true if it is easy to determine this account should consider having rent collected from it

pub fn get_rent_due(&self, account: &impl ReadableAccount) -> (u64, bool)

given an account that ‘should_collect_rent’ returns (amount rent due, is_exempt_from_rent)

    &self,
    address: &Pubkey,
    account: &mut AccountSharedData,
    rent_for_sysvars: bool,
