Enum solana_accounts_db::accounts_index::PreAllocatedAccountMapEntry

pub enum PreAllocatedAccountMapEntry<T: IndexValue> {
    Entry(Arc<AccountMapEntryInner<T>>),
    Raw((Slot, T)),
}

can be used to pre-allocate structures for insertion into accounts index outside of lock

Variants

Entry(Arc<AccountMapEntryInner<T>>)

Raw((Slot, T))

Implementations

impl<T: IndexValue> PreAllocatedAccountMapEntry<T>

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.

pub fn into_account_map_entry<U: DiskIndexValue + From<T> + Into<T>>( self, storage: &Arc<BucketMapHolder<T, U>> ) -> Arc<AccountMapEntryInner<T>>

Trait Implementations

impl<T: IndexValue> From<PreAllocatedAccountMapEntry<T>> for (Slot, T)

fn from(source: PreAllocatedAccountMapEntry<T>) -> (Slot, T)

Converts to this type from the input type.
