Struct ThrottleSpec 

Source
pub struct ThrottleSpec {
    pub high: f64,
    pub low: Option<f64>,
    pub control: String,
    pub start: Option<f64>,
    pub floor: f64,
    pub window: String,
}
Expand description

Adaptive backpressure governor parameters (SRD-83 §throttle). The governor keeps the WINDOWED attempt-failure fraction — the see-through-retries saturation signal — under high by walking the named dynamic control down multiplicatively, and recovers it toward the authored ceiling while the window stays under low.

Fields§

§high: f64

Windowed attempt-failure fraction that triggers a back-off.

§low: Option<f64>

Fraction below which the governor recovers toward the authored ceiling. Default: high / 5.

§control: String

The dynamic control to walk: concurrency (default) or rate.

§start: Option<f64>

Initial offered value (slow-start seed). Default: floor — the governor assumes the most fragile target and PROVES headroom by doubling through clean windows. Declare a higher start only for targets known to be robust at phase entry.

§floor: f64

Never throttle below this value.

§window: String

Evaluation window (duration string, e.g. “2s”).
