Struct Account

#[repr(C)]
pub struct Account {
    pub lamports: u64,
    pub data: Vec<u8>,
    pub owner: Pubkey,
    pub executable: bool,
    pub rent_epoch: u64,
}

An Account with data that is stored on chain

Fields

lamports: u64

lamports in the account

data: Vec<u8>

data held in this account

owner: Pubkey

the program that owns this account. If executable, the program that loads this account.

executable: bool

this account’s data contains a loaded program (and is now read-only)

rent_epoch: u64

the epoch at which this account will next owe rent

Trait Implementations

impl AbiExample for Account

fn example() -> Account

impl Account for Account

Return the information required to construct an AccountInfo. Used by the AccountInfo conversion implementations.

fn get(&mut self) -> (&mut u64, &mut [u8], &Pubkey, bool, u64)

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<(), Error>

Formats the value using the given formatter.

impl Default for Account

fn default() -> Account

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Account

fn deserialize<__D>( __deserializer: __D, ) -> Result<Account, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AccountSharedData> for Account

fn from(other: AccountSharedData) -> Account

Converts to this type from the input type.

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 ReadableAccount for Account

fn lamports(&self) -> u64

fn data(&self) -> &[u8]

fn owner(&self) -> &Pubkey

fn executable(&self) -> bool

fn rent_epoch(&self) -> u64

fn to_account_shared_data(&self) -> AccountSharedData

impl Serialize for Account

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> StateMut<T> for Account

where T: Serialize + DeserializeOwned,

fn state(&self) -> Result<T, InstructionError>

fn set_state(&mut self, state: &T) -> Result<(), InstructionError>
