Struct solana_program::rent::Rent[][src]

#[repr(C)]pub struct Rent {
    pub lamports_per_byte_year: u64,
    pub exemption_threshold: f64,
    pub burn_percent: u8,
}

Fields

lamports_per_byte_year: u64

Rental rate

exemption_threshold: f64

exemption threshold, in years

burn_percent: u8

Implementations

impl Rent[src]

pub fn calculate_burn(&self, rent_collected: u64) -> (u64, u64)[src]

calculate how much rent to burn from the collected rent

pub fn minimum_balance(&self, data_len: usize) -> u64[src]

minimum balance due for a given size Account::data.len()

Note: a stripped-down version of this calculation is used in calculate_split_rent_exempt_reserve in the stake program. When this function is updated, – eg. when making rent variable – the stake program will need to be refactored

pub fn is_exempt(&self, balance: u64, data_len: usize) -> bool[src]

whether a given balance and data_len would be exempt

pub fn due(
    &self,
    balance: u64,
    data_len: usize,
    years_elapsed: f64
) -> (u64, bool)
[src]

rent due on account’s data_len with balance

pub fn free() -> Self[src]
