Implementations

impl MultipleSlots

pub(crate) fn set_storage_capacity_when_created_pow2( &mut self, storage_capacity_when_created_pow2: u8 )

pub(crate) fn set_storage_offset(&mut self, storage_offset: u64)

fn storage_capacity_when_created_pow2(&self) -> u8

fn storage_offset(&self) -> u64

pub(crate) fn num_slots(&self) -> Slot

pub(crate) fn set_num_slots(&mut self, num_slots: Slot)

pub(crate) fn data_bucket_ix(&self) -> u64

pub(crate) fn data_bucket_from_num_slots(num_slots: Slot) -> u64

return closest bucket index fit for the slot slice. Since bucket size is 2^index, the return value is min index, such that 2^index >= num_slots index = ceiling(log2(num_slots)) special case, when slot slice empty, return 0th index.

pub(crate) fn data_loc(&self, storage: &BucketStorage<BucketWithHeader>) -> u64

This function maps the original data location into an index in the current bucket storage. This is coupled with how we resize bucket storages.

pub fn set_ref_count( data_bucket: &mut BucketStorage<BucketWithHeader>, data_ix: u64, ref_count: RefCount )

ref_count is stored in the header per cell, in packed_ref_count

pub fn ref_count( data_bucket: &BucketStorage<BucketWithHeader>, data_ix: u64 ) -> RefCount

ref_count is stored in the header per cell, in packed_ref_count

Trait Implementations

impl Clone for MultipleSlots

fn clone(&self) -> MultipleSlots

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MultipleSlots

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

Formats the value using the given formatter.

impl Default for MultipleSlots

fn default() -> MultipleSlots

Returns the “default value” for a type.

impl PartialEq<MultipleSlots> for MultipleSlots

fn eq(&self, other: &MultipleSlots) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
