Struct HotAccountMeta

#[repr(C)]
pub struct HotAccountMeta { /* private fields */ }

The storage and in-memory representation of the metadata entry for a hot account.

Trait Implementations

impl Clone for HotAccountMeta

fn clone(&self) -> HotAccountMeta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HotAccountMeta

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

Formats the value using the given formatter.

impl PartialEq for HotAccountMeta

fn eq(&self, other: &HotAccountMeta) -> 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 TieredAccountMeta for HotAccountMeta

fn new() -> Self

Construct a HotAccountMeta instance.

fn with_lamports(self, lamports: u64) -> Self

A builder function that initializes lamports.

fn with_account_data_padding(self, padding: u8) -> Self

A builder function that initializes the number of padding bytes for the account data associated with the current meta.

fn with_owner_offset(self, owner_offset: OwnerOffset) -> Self

A builder function that initializes the owner’s index.

fn with_account_data_size(self, _account_data_size: u64) -> Self

A builder function that initializes the account data size.

fn with_flags(self, flags: &AccountMetaFlags) -> Self

A builder function that initializes the AccountMetaFlags of the current meta.

fn lamports(&self) -> u64

Returns the balance of the lamports associated with the account.

fn account_data_padding(&self) -> u8

Returns the number of padding bytes for the associated account data

fn owner_offset(&self) -> OwnerOffset

Returns the index to the accounts’ owner in the current AccountsFile.

fn flags(&self) -> &AccountMetaFlags

Returns the AccountMetaFlags of the current meta.

fn supports_shared_account_block() -> bool

Always returns false as HotAccountMeta does not support multiple meta entries sharing the same account block.

fn rent_epoch(&self, account_block: &[u8]) -> Option<Epoch>

Returns the epoch that this account will next owe rent by parsing the specified account block. None will be returned if this account does not persist this optional field.

fn final_rent_epoch(&self, account_block: &[u8]) -> Epoch

Returns the epoch that this account will next owe rent by parsing the specified account block. RENT_EXEMPT_RENT_EPOCH will be returned if the account is rent-exempt.

For a zero-lamport account, Epoch::default() will be returned to default states of an AccountSharedData.

fn optional_fields_offset(&self, account_block: &[u8]) -> usize

Returns the offset of the optional fields based on the specified account block.

fn account_data_size(&self, account_block: &[u8]) -> usize

Returns the length of the data associated to this account based on the specified account block.

fn account_data<'a>(&self, account_block: &'a [u8]) -> &'a [u8]

Returns the data associated to this account based on the specified account block.

impl Zeroable for HotAccountMeta

fn zeroed() -> Self

Calls zeroed.

impl Copy for HotAccountMeta

impl Eq for HotAccountMeta

impl Pod for HotAccountMeta
