Struct StorableAccountsBySlot

pub struct StorableAccountsBySlot<'a> { /* private fields */ }

holds slices of accounts being moved FROM a common source slot to ‘target_slot’

Implementations

impl<'a> StorableAccountsBySlot<'a>

pub fn new( target_slot: Slot, slots_and_accounts: &'a [(Slot, &'a [&'a AccountFromStorage])], db: &'a AccountsDb, ) -> Self

each element of slots_and_accounts is (source slot, accounts moving FROM source slot)

Trait Implementations

impl<'a> StorableAccounts<'a> for StorableAccountsBySlot<'a>

fn account<Ret>( &self, index: usize, callback: impl for<'local> FnMut(AccountForStorage<'local>) -> Ret, ) -> Ret

account at ‘index’

fn slot(&self, index: usize) -> Slot

fn target_slot(&self) -> Slot

slot that all accounts are to be written to

fn len(&self) -> usize

accounts to write

fn contains_multiple_slots(&self) -> bool

are there accounts from multiple slots only used for an assert

fn account_default_if_zero_lamport<Ret>( &self, index: usize, callback: impl for<'local> FnMut(AccountForStorage<'local>) -> Ret, ) -> Ret

None if account is zero lamports

fn is_empty(&self) -> bool

true if no accounts to write
