Implementations§

source§

impl BucketMapHolderStats

source

pub fn new(bins: usize) -> BucketMapHolderStats

source

pub fn inc_insert(&self)

source

pub fn inc_insert_count(&self, count: u64)

source

pub fn inc_delete(&self)

source

pub fn inc_mem_count(&self, bin: usize)

source

pub fn dec_mem_count(&self, bin: usize)

source

pub fn add_mem_count(&self, bin: usize, count: usize)

source

pub fn sub_mem_count(&self, bin: usize, count: usize)

source

pub fn remaining_until_next_interval(&self) -> u64

source

pub fn total_count(&self) -> usize

source

pub fn count_in_bucket(&self, bucket: usize) -> usize

source

pub fn get_remaining_items_to_flush_estimate(&self) -> usize

This is an estimate of the # of items in mem that are awaiting flushing to disk. returns (# items in mem) - (# items we intend to hold in mem for performance heuristics) The result is also an estimate because ‘held_in_mem’ is based on a stat that is swapped out when stats are reported.

pub fn report_stats<T: IndexValue, U: DiskIndexValue + From<T> + Into<T>>( &self, storage: &BucketMapHolder<T, U>, )
