Struct ResizerConfig 

pub struct ResizerConfig {
    pub lower_bound: usize,
    pub upper_bound: usize,
    pub pressure_threshold: f64,
    pub backoff_threshold: f64,
    pub rampup_rate: f64,

Fields

lower_bound: usize

upper_bound: usize

pressure_threshold: f64

Fraction of busy routees that triggers growth (0.0..=1.0).

backoff_threshold: f64

Fraction of routees needed to be idle to trigger backoff.

rampup_rate: f64

Multiplicative ramp-up factor applied to the current size.

backoff_rate: f64

Multiplicative ramp-down factor applied to the current size.

messages_per_resize: u64

How many messages must be processed before checking pressure again.

backoff_delay: Duration

Idle interval before considering a backoff resize.

Implementations

impl ResizerConfig

pub fn compute_delta(&self, current_size: usize, busy: usize) -> ResizeAdvice

Decide how many routees to add or remove given the current pool size and the count of currently-busy routees. Returns the net delta clamped to [lower_bound, upper_bound].

Trait Implementations

impl Clone for ResizerConfig

fn clone(&self) -> ResizerConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResizerConfig

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

Formats the value using the given formatter.

impl Default for ResizerConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ResizerConfig

fn eq(&self, other: &ResizerConfig) -> 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.
