Account information
Fields
key: &'a Pubkey
Public key of the account
is_signer: bool
Was the transaction signed by this account’s public key?
is_writable: bool
Is the account writable?
lamports: Rc<RefCell<&'a mut u64>>
The lamports in the account. Modifiable by programs.
data: Rc<RefCell<&'a mut [u8]>>
The data held in this account. Modifiable by programs.
owner: &'a Pubkey
Program that owns this account
executable: bool
This account’s data contains a loaded program (and is now read-only)
rent_epoch: u64
The epoch at which this account will next owe rent
