Struct AutoscaleState 

pub struct AutoscaleState {
    pub arrival_rate: Ewma,
    pub target: Option<u32>,
    pub last_desired: u32,
    /* private fields */
}

Per-pool autoscaler state: smoothed rates, the last target and the history used for scale-down stabilization.

Fields

arrival_rate: Ewma

Smoothed arrival rate (tasks per second).

target: Option<u32>

Last requested target.

last_desired: u32

Desired capacity computed at the last evaluation (before step limits).

Implementations

impl AutoscaleState

pub fn desired(&mut self, cfg: &AutoscaleConfig, s: &Signals) -> u32

Unclamped-by-step desired capacity from the signals.

pub fn evaluate( &mut self, cfg: &AutoscaleConfig, s: &Signals, now: Time, ) -> Option<u32>

Evaluates the policy; returns a new target when it changes.

Trait Implementations

impl Debug for AutoscaleState

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

Formats the value using the given formatter.

impl Default for AutoscaleState

fn default() -> Self

Returns the “default value” for a type.
