Account information


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: Epoch

The epoch at which this account will next owe rent
