Struct LoadBalance 

pub struct LoadBalance<K> { /* private fields */ }

Result of load balancing - tracks loads per item and computes unfairness.

Unfairness is the square root of sum of squared deviations from mean. Lower values indicate fairer distribution. Zero means perfectly balanced.

Implementations

impl<K> LoadBalance<K>

pub fn loads(&self) -> &HashMap<K, i64>

Returns map of balanced items to their total load.

pub fn unfairness(&self) -> i64

Returns unfairness as i64 for use with of_soft(). This is the raw value - of_soft() handles decimal scaling.

Trait Implementations

impl<K: Clone + Eq + Hash + Send + Sync> Accumulator<(K, i64), LoadBalance<K>> for LoadBalanceAccumulator<K>

fn accumulate(&mut self, value: &(K, i64))

Adds a value to the accumulator.

fn retract(&mut self, value: &(K, i64))

Removes a value from the accumulator.

fn finish(&self) -> LoadBalance<K>

Produces the final result.

fn reset(&mut self)

Resets the accumulator to its initial state.

impl<K: Clone> Clone for LoadBalance<K>

fn clone(&self) -> LoadBalance<K>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for LoadBalance<K>

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

Formats the value using the given formatter.
