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 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 duplicate 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

Available on crate feature serde only.

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>

impl WritableAccount for Account

fn set_lamports(&mut self, lamports: u64)

fn data_as_mut_slice(&mut self) -> &mut [u8]

fn set_owner(&mut self, owner: Pubkey)
