Struct ProgramState 

pub struct ProgramState<'info, T: AccountSerialize + AccountDeserialize + Clone> { /* private fields */ }

👎Deprecated

Boxed container for the program state singleton.

Implementations

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

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,

fn try_accounts( program_id: &Pubkey, accounts: &mut &[AccountInfo<'info>], _ix_data: &[u8], ) -> Result<Self, 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: AccountSerialize + AccountDeserialize + Clone> AccountsExit<'info> for ProgramState<'info, T>

fn exit(&self, _program_id: &Pubkey) -> ProgramResult

program_id is the currently executing program.

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

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

Converts this type into a shared reference of the (usually inferred) input type.

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

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

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

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'info, T> From<CpiAccount<'info, T>> for ProgramState<'info, T>

where T: AccountSerialize + AccountDeserialize + Clone,

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

Converts to this type from the input type.

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

fn key(&self) -> Pubkey

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

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

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

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

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

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

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.
