Struct Account 

#[repr(C)]
pub struct Account {
    pub lamports: u64,
    pub data: Vec<u8>,
    pub owner: Pubkey,
    pub executable: bool,
    pub rent_epoch: Epoch,
}

An on-chain account with owned data and an explicit rent epoch.

Fields

lamports: u64

data: Vec<u8>

Data held in the account.

owner: Pubkey

The program that owns this account.

executable: bool

Whether the account contains executable program data.

rent_epoch: Epoch

The epoch at which this account next owes rent.

Implementations

impl Account

pub fn new(lamports: u64, space: usize, owner: &Pubkey) -> Self

pub fn new_ref(lamports: u64, space: usize, owner: &Pubkey) -> Rc<RefCell<Self>>

Creates a new account wrapped in a RefCell.

pub fn new_rent_epoch( lamports: u64, space: usize, owner: &Pubkey, rent_epoch: Epoch, ) -> Self

Creates a new account with an explicit rent epoch.
