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: Epoch

The epoch at which this account will next owe rent

Implementations

Realloc the account’s data and optionally zero-initialize the new memory.

Note: Account data can be increased within a single call by up to solana_program::entrypoint::MAX_PERMITTED_DATA_INCREASE bytes.

Note: Memory used to grow is already zero-initialized upon program entrypoint and re-zeroing it wastes compute units. If within the same call a program reallocs from larger to smaller and back to larger again the new space could contain stale data. Pass true for zero_init in this case, otherwise compute units will be wasted re-zero-initializing.
