Enum PreAllocatedAccountMapEntry

Source
pub enum PreAllocatedAccountMapEntry<T: IndexValue> {

    Raw((Slot, T)),
}
Expand description

Raw((Slot, T))

Implementations§

Source§

impl<T: IndexValue> PreAllocatedAccountMapEntry<T>

Source

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

create an entry that is equivalent to this process:

  1. new empty (refcount=0, slot_list={})
  2. update(slot, account_info)

This code is called when the first entry [ie. (slot,account_info)] for a pubkey is inserted into the index.
