Struct LoadBalancePlan

Source

pub struct LoadBalancePlan {
    pub ranges: Vec<Range<usize>>,
    pub weights: Vec<f64>,
}

Expand description

Result of load balancing: a set of ranges assigned to workers.

Fields§

§ranges: Vec<Range<usize>>

Ranges for each worker.

§weights: Vec<f64>

Total weight assigned to each worker (for Weighted strategy).

Implementations§

Source §

impl LoadBalancePlan

Source

pub fn num_workers(&self) -> usize

Number of workers in this plan.

Source

pub fn max_weight(&self) -> f64

Maximum weight across workers (a measure of imbalance).

Source

pub fn imbalance_ratio(&self) -> f64

Imbalance ratio: max_weight / avg_weight. 1.0 is perfect balance.
