Struct Mod 

pub struct Mod<const NUM: usize = 3, const DEN: usize = 2> { /* private fields */ }

Grow by the rational factor NUM / DEN and map with a modulo.

The factor must be at least 1.1. The default is 3/2.

Trait Implementations

impl<const NUM: usize, const DEN: usize> Clone for Mod<NUM, DEN>

fn clone(&self) -> Mod<NUM, DEN>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const NUM: usize, const DEN: usize> GrowthPolicy for Mod<NUM, DEN>

fn new(min_bucket_count: usize) -> Result<(Self, usize), LengthError>

Build a policy for at least min_bucket_count buckets.

fn bucket_for_hash(&self, hash: usize) -> usize

Map hash to a bucket in [0, bucket_count).

fn next_bucket_count(&self) -> Result<usize, LengthError>

The bucket count to use on the next growth.

fn max_bucket_count(&self) -> usize

The largest bucket count the policy can represent.

fn clear(&mut self)

Reset the policy to the state of a 0-bucket table.

fn is_power_of_two() -> bool

Whether this policy keeps the bucket count a power of two.
