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

Trait Implementations

impl<'info> Accounts<'info> for AccountInfo<'info>

pub fn try_accounts(
    _program_id: &Pubkey,
    accounts: &mut &[AccountInfo<'info>],
    _ix_data: &[u8]
) -> Result<AccountInfo<'info>, ProgramError>

Returns the validated accounts struct. What constitutes “valid” is program dependent. However, users of these types should never have to worry about account substitution attacks. For example, if a program expects a Mint account from the SPL token program in a particular field, then it should be impossible for this method to return Ok if any other account type is given–from the SPL token program or elsewhere.

pub fn exit(&self, _program_id: &Pubkey) -> Result<(), ProgramError>

program_id is the currently executing program.

Performs the conversion.

impl<'info, T> AsRef<AccountInfo<'info>> for Loader<'info, T> where
    T: ZeroCopy, 

pub fn as_ref(&self) -> &AccountInfo<'info>

Performs the conversion.

impl<'info> Key for AccountInfo<'info>

pub fn key(&self) -> Pubkey

impl<'info> ToAccountInfo<'info> for AccountInfo<'info>

pub fn to_account_info(&self) -> AccountInfo<'info>

impl<'info> ToAccountInfos<'info> for AccountInfo<'info>

pub fn to_account_infos(&self) -> Vec<AccountInfo<'info>, Global>

impl<'info> ToAccountMetas for AccountInfo<'info>

pub fn to_account_metas(
    &self,
    is_signer: Option<bool>
) -> Vec<AccountMeta, Global>

is_signer is given as an optional override for the signer meta field. This covers the edge case when a program-derived-address needs to relay a transaction from a client to another program but sign the transaction before the relay. The client cannot mark the field as a signer, and so we have to override the is_signer meta field given by the client.
