Struct solana_runtime::in_mem_accounts_index::InMemAccountsIndex

pub struct InMemAccountsIndex<T: IndexValue, U: DiskIndexValue + From<T> + Into<T>> { /* private fields */ }

Implementations

impl<T: IndexValue, U: DiskIndexValue + From<T> + Into<T>> InMemAccountsIndex<T, U>

pub fn new(storage: &Arc<BucketMapHolder<T, U>>, bin: usize) -> Self

pub fn shrink_to_fit(&self)

Release entire in-mem hashmap to free all memory associated with it. Idea is that during startup we needed a larger map than we need during runtime. When using disk-buckets, in-mem index grows over time with dynamic use and then shrinks, in theory back to 0.

pub fn items<R>(&self, range: &R) -> Vec<(Pubkey, Arc<AccountMapEntryInner<T>>)>where R: RangeBounds<Pubkey> + Debug,

pub fn keys(&self) -> Vec<Pubkey>

pub fn get(&self, pubkey: &Pubkey) -> Option<Arc<AccountMapEntryInner<T>>>

lookup ‘pubkey’ in index (in mem or on disk)

pub fn remove_if_slot_list_empty(&self, pubkey: Pubkey) -> bool

pub fn slot_list_mut<RT>( &self, pubkey: &Pubkey, user: impl for<'a> FnOnce(&mut RwLockWriteGuard<'a, SlotList<T>>) -> RT ) -> Option<RT>

pub fn upsert( &self, pubkey: &Pubkey, new_value: PreAllocatedAccountMapEntry<T>, other_slot: Option<Slot>, reclaims: &mut SlotList<T>, reclaim: UpsertReclaim )

pub fn len_for_stats(&self) -> usize

pub fn startup_insert_only( &self, slot: Slot, items: impl Iterator<Item = (Pubkey, T)> )

Queue up these insertions for when the flush thread is dealing with this bin. This is very fast and requires no lookups or disk access.

pub fn insert_new_entry_if_missing_with_lock( &self, pubkey: Pubkey, new_entry: PreAllocatedAccountMapEntry<T> ) -> InsertNewEntryResults

pub fn hold_range_in_memory<R>(&self, range: &R, start_holding: bool)where R: RangeBounds<Pubkey> + Debug,

if ‘start_holding’=true, then: at the end of this function, cache_ranges_held will be updated to contain ‘range’ and all pubkeys in that range will be in the in-mem cache if ‘start_holding’=false, then: ‘range’ will be removed from cache_ranges_held and all pubkeys will be eligible for being removed from in-mem cache in the bg if no other range is holding them Any in-process flush will be aborted when it gets to evicting items from in-mem.

pub fn stats(&self) -> &BucketMapHolderStats

pub fn update_time_stat(stat: &AtomicU64, m: Measure)

Trait Implementations

impl<T: IndexValue, U: DiskIndexValue + From<T> + Into<T>> Debug for InMemAccountsIndex<T, U>

fn fmt(&self, _f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
