Struct AccountMapEntryInner

source
pub struct AccountMapEntryInner<T> {
    pub slot_list: RwLock<SlotList<T>>,
    pub meta: AccountMapEntryMeta,
    /* private fields */
}
Expand description

one entry in the in-mem accounts index Represents the value for an account key in the in-memory accounts index

Fields§

§slot_list: RwLock<SlotList<T>>

list of slots in which this pubkey was updated Note that ‘clean’ removes outdated entries (ie. older roots) from this slot_list purge_slot() also removes non-rooted slots from this list

§meta: AccountMapEntryMeta

synchronization metadata for in-memory state since last flush to disk accounts index

Implementations§

source§

impl<T: IndexValue> AccountMapEntryInner<T>

source

pub fn new( slot_list: SlotList<T>, ref_count: RefCount, meta: AccountMapEntryMeta, ) -> Self

source

pub fn ref_count(&self) -> RefCount

source

pub fn addref(&self)

source

pub fn unref(&self) -> bool

decrement the ref count return true if the old refcount was already 0. This indicates an under refcounting error in the system.

source

pub fn dirty(&self) -> bool

source

pub fn set_dirty(&self, value: bool)

source

pub fn clear_dirty(&self) -> bool

set dirty to false, return true if was dirty

source

pub fn age(&self) -> Age

source

pub fn set_age(&self, value: Age)

source

pub fn try_exchange_age(&self, next_age: Age, expected_age: Age)

set age to ‘next_age’ if ‘self.age’ is ‘expected_age’
