Implementations

impl<T: IndexValue> BucketMapHolder<T>

pub fn is_disk_index_enabled(&self) -> bool

is the accounts index using disk as a backing store

pub fn increment_age(&self)

pub fn future_age_to_flush(&self) -> Age

pub fn get_startup(&self) -> bool

used by bg processes to determine # active threads and how aggressively to flush

pub fn set_startup(&self, value: bool)

startup=true causes: in mem to act in a way that flushes to disk asap startup=false is ‘normal’ operation

pub fn current_age(&self) -> Age

pub fn bucket_flushed_at_current_age(&self, can_advance_age: bool)

pub fn all_buckets_flushed_at_current_age(&self) -> bool

have all buckets been flushed at the current age?

pub fn count_buckets_flushed(&self) -> usize

pub fn maybe_advance_age(&self) -> bool

if all buckets are flushed at the current age and time has elapsed, then advance age

pub fn new(
    bins: usize,
    config: &Option<AccountsIndexConfig>,
    threads: usize
) -> Self

pub fn next_bucket_to_flush(&self) -> usize

pub fn background(
    &self,
    exit: Arc<AtomicBool>,
    in_mem: Vec<Arc<InMemAccountsIndex<T>>>,
    can_advance_age: bool
)

impl<T: IndexValue> Debug for BucketMapHolder<T>

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

Formats the value using the given formatter.
