Boxed container for the program state singleton.

Implementations

impl<'a, T> ProgramState<'a, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

pub fn try_from(
    program_id: &Pubkey,
    info: &AccountInfo<'a>
) -> Result<ProgramState<'a, T>, ProgramError>

Deserializes the given info into a ProgramState.

pub fn seed() -> &'static str

pub fn address(program_id: &Pubkey) -> Pubkey

Trait Implementations

impl<'info, T> Accounts<'info> for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

pub fn try_accounts(
    program_id: &Pubkey,
    accounts: &mut &[AccountInfo<'info>],
    _ix_data: &[u8]
) -> Result<ProgramState<'info, T>, 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.

impl<'info, T> AccountsExit<'info> for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

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

program_id is the currently executing program.

impl<'info, T> AsRef<AccountInfo<'info>> for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

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

Performs the conversion.

impl<'info, T> Clone for ProgramState<'info, T> where
    T: Clone + AccountSerialize + AccountDeserialize, 

pub fn clone(&self) -> ProgramState<'info, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T> Deref for ProgramState<'a, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

type Target = T

The resulting type after dereferencing.

pub fn deref(&self) -> &<ProgramState<'a, T> as Deref>::Target

Dereferences the value.

impl<'a, T> DerefMut for ProgramState<'a, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

pub fn deref_mut(&mut self) -> &mut <ProgramState<'a, T> as Deref>::Target

Mutably dereferences the value.

impl<'info, T> From<CpiAccount<'info, T>> for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

pub fn from(a: CpiAccount<'info, T>) -> ProgramState<'info, T>

Performs the conversion.

impl<'info, T> Key for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

pub fn key(&self) -> Pubkey

impl<'info, T> ToAccountInfo<'info> for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

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

impl<'info, T> ToAccountInfos<'info> for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

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

impl<'info, T> ToAccountMetas for ProgramState<'info, T> where
    T: AccountSerialize + AccountDeserialize + Clone, 

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.
