Struct DenseStore 

pub struct DenseStore { /* private fields */ }

A dense store using contiguous array storage.

This store grows unbounded to accommodate any range of indices. It’s memory-efficient when the indices are clustered together, but can use significant memory if indices are widely scattered.

Use this store when:

• You have a bounded range of input values
• Memory usage is not a concern
• You need the fastest possible insertion performance

Implementations

impl DenseStore

pub fn new() -> Self

Creates an empty DenseStore.

Trait Implementations

impl Clone for DenseStore

fn clone(&self) -> DenseStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DenseStore

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

Formats the value using the given formatter.

impl Default for DenseStore

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DenseStore

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Store for DenseStore

fn add(&mut self, index: i32, count: u64)

Adds a count to the bin at the given index.

fn total_count(&self) -> u64

Returns the total count across all bins.

fn min_index(&self) -> Option<i32>

Returns the minimum index with a non-zero count, or None if empty.

fn max_index(&self) -> Option<i32>

Returns the maximum index with a non-zero count, or None if empty.

fn key_at_rank(&self, rank: u64) -> Option<i32>

Returns the index of the bin containing the given rank.

fn merge(&mut self, other: &Self)

Merges another store into this one.

fn is_empty(&self) -> bool

Returns true if the store is empty.

fn clear(&mut self)

Clears all bins from the store.

fn merge_from_proto( &mut self, proto: &ProtoStore, ) -> Result<(), ProtoConversionError>

Populates this store from a protobuf Store.

fn to_proto(&self) -> ProtoStore

Converts this store to a protobuf Store.
