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

calculate how much rent to burn from the collected rent

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

whether a given balance and data_len would be exempt

rent due on account’s data_len with balance
