Implementations

source

impl<T: IndexValue> PreAllocatedAccountMapEntry<T>

source

pub fn new(
 slot: Slot,
 account_info: T,
 storage: &Arc<BucketMapHolder<T>>,
 store_raw: bool
) -> PreAllocatedAccountMapEntry<T>

create an entry that is equivalent to this process:

new empty (refcount=0, slot_list={})
update(slot, account_info) This code is called when the first entry [ie. (slot,account_info)] for a pubkey is inserted into the index.
