Struct AdaptiveConfig 

pub struct AdaptiveConfig {
    pub enabled: bool,
    pub min_concurrency: usize,
    pub max: ChannelMax,
    pub window_ops: usize,
    pub min_window_ops: usize,
    pub success_target: f64,
    pub timeout_ceiling: f64,
    pub latency_inflation_factor: f64,
    pub latency_ewma_alpha: f64,
}

Tunable knobs for the adaptive controller. Defaults are picked so that the controller behaves at least as well as the prior static defaults on a healthy network: starts at the previous static value and only deviates when signals demand it.

Fields

enabled: bool

Master switch. When false, channels report initial forever and ignore observations. Useful for benchmarks / debugging.

min_concurrency: usize

Floor concurrency per channel. Never go below this.

max: ChannelMax

Per-channel ceiling concurrency. See ChannelMax.

window_ops: usize

Sliding window size in number of recent ops considered for adaptation decisions.

min_window_ops: usize

Below this count of outcomes in the window, hold steady.

success_target: f64

Required success rate to consider the window healthy. Healthy windows trigger increase; unhealthy windows trigger decrease.

timeout_ceiling: f64

Timeout rate above which the window counts as stressed even if the success rate would otherwise pass.

latency_inflation_factor: f64

p95 latency above latency_inflation_factor * baseline is a stress signal. Baseline is an EWMA of healthy-window p95s.

latency_ewma_alpha: f64

EWMA smoothing factor for the latency baseline. 0 = never updates, 1 = baseline = last sample. 0.2 trades responsiveness for stability. Validated to [0.0, 1.0]; NaN/non-finite values are sanitized to the default at controller construction.

Implementations

impl AdaptiveConfig

pub fn sanitize(&mut self)

Sanitize the config: clamp latency_ewma_alpha to [0,1] (rejecting NaN/Inf which would otherwise panic in Duration::from_secs_f64), enforce min_concurrency >= 1, enforce per-channel max >= min_concurrency, enforce min_window_ops <= window_ops. Idempotent.

Trait Implementations

impl Clone for AdaptiveConfig

fn clone(&self) -> AdaptiveConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdaptiveConfig

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

Formats the value using the given formatter.

impl Default for AdaptiveConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AdaptiveConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for AdaptiveConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
