Struct Account

#[repr(C)]
pub struct Account {
    pub mint: Pubkey,
    pub owner: Pubkey,
    pub amount: u64,
    pub delegate: COption<Pubkey>,
    pub state: AccountState,
    pub is_native: COption<u64>,
    pub delegated_amount: u64,
    pub close_authority: COption<Pubkey>,
}

Account data.

Fields

mint: Pubkey

The mint associated with this account

owner: Pubkey

The owner of this account.

amount: u64

The amount of tokens this account holds.

delegate: COption<Pubkey>

If delegate is Some then delegated_amount represents the amount authorized by the delegate

state: AccountState

The account’s state

is_native: COption<u64>

If is_native.is_some, this is a native token, and the value logs the rent-exempt reserve. An Account is required to be rent-exempt, so the value is used by the Processor to ensure that wrapped SOL accounts do not drop below this threshold.

delegated_amount: u64

The amount delegated

close_authority: COption<Pubkey>

Optional authority to close the account.

Implementations

impl Account

pub fn is_frozen(&self) -> bool

Checks if account is frozen

pub fn is_native(&self) -> bool

Checks if account is native

pub fn is_owned_by_system_program_or_incinerator(&self) -> bool

Checks if a token Account’s owner is the system_program or the incinerator

Trait Implementations

impl Clone for Account

fn clone(&self) -> Account

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Account

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Account

fn default() -> Account

Returns the “default value” for a type.

impl GenericTokenAccount for Account

fn valid_account_data(account_data: &[u8]) -> bool

Check if the account data is a valid token account

fn unpack_account_owner_unchecked(account_data: &[u8]) -> &Pubkey

Call after account length has already been verified to unpack the account owner

fn unpack_account_mint_unchecked(account_data: &[u8]) -> &Pubkey

Call after account length has already been verified to unpack the account mint

fn unpack_pubkey_unchecked(account_data: &[u8], offset: usize) -> &Pubkey

Call after account length has already been verified to unpack a Pubkey at the specified offset. Panics if account_data.len() is less than PUBKEY_BYTES

fn unpack_account_owner(account_data: &[u8]) -> Option<&Pubkey>

Unpacks an account’s owner from opaque account data.

fn unpack_account_mint(account_data: &[u8]) -> Option<&Pubkey>

Unpacks an account’s mint from opaque account data.

impl IsInitialized for Account

fn is_initialized(&self) -> bool

Is initialized

impl Pack for Account

const LEN: usize = 165usize

The length, in bytes, of the packed representation

fn get_packed_len() -> usize

Get the packed length

fn unpack(input: &[u8]) -> Result<Self, ProgramError>

where Self: IsInitialized,

Unpack from slice and check if initialized

fn unpack_unchecked(input: &[u8]) -> Result<Self, ProgramError>

Unpack from slice without checking if initialized

fn pack(src: Self, dst: &mut [u8]) -> Result<(), ProgramError>

Pack into slice

impl PartialEq for Account

fn eq(&self, other: &Account) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Account

impl Sealed for Account

impl StructuralPartialEq for Account
