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 StoredAccountMeta<'a>])], ) -> Self

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

Trait Implementations

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

fn pubkey(&self, index: usize) -> &Pubkey

pubkey at ‘index’

fn account(&self, index: usize) -> &StoredAccountMeta<'a>

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 has_hash_and_write_version(&self) -> bool

true iff the impl can provide hash and write_version Otherwise, hash and write_version have to be provided separately to store functions.

fn hash(&self, index: usize) -> &AccountHash

return hash for account at ‘index’ Should only be called if ‘has_hash_and_write_version’ = true

fn write_version(&self, index: usize) -> u64

return write_version for account at ‘index’ Should only be called if ‘has_hash_and_write_version’ = true

fn account_default_if_zero_lamport(&self, index: usize) -> Option<&T>

None if account is zero lamports

fn is_empty(&self) -> bool

true if no accounts to write
