Enum BackpressureLevel 

pub enum BackpressureLevel {
    None,
    Low,
    Medium,
    High,
    Critical,
}

The current backpressure state of a node.

Variants

None

No backpressure; producer may run at full rate.

Low

Mild backpressure; producer should throttle slightly.

Medium

Moderate backpressure; producer should throttle significantly.

High

Severe backpressure; producer should pause.

Critical

Critical backpressure; producer must stop immediately.

Implementations

impl BackpressureLevel

pub fn rate_multiplier(&self) -> f64

Recommended rate multiplier (fraction of nominal rate to apply).

1.0 = no throttling; 0.0 = stop completely.

pub fn from_fill_ratio(ratio: f64) -> Self

Derive a backpressure level from a queue fill ratio (0.0–1.0).
