Struct DegradationController 

pub struct DegradationController<M: ResourceMonitor> { /* private fields */ }

Graceful degradation controller that wraps a ResourceMonitor and makes admission-control decisions.

Implementations

impl<M: ResourceMonitor> DegradationController<M>

pub fn new(monitor: M, elevated_batch_factor: f64) -> Self

Create a new controller with the given resource monitor.

elevated_batch_factor is multiplied by the normal batch size when pressure is elevated (e.g. 0.5 halves the batch).

pub fn pressure(&self) -> PressureLevel

Return the current pressure level.

pub fn monitor(&self) -> &M

Return a reference to the underlying monitor.

pub fn elevated_batch_factor(&self) -> f64

Return the elevated batch factor.

pub fn admit_spawn(&self) -> DegradationDecision

Decide whether a new child actor spawn should be admitted.

pub fn effective_batch_size(&self, normal: usize) -> usize

Compute the effective batch size given normal and current pressure.

pub fn should_pause_non_essential(&self) -> bool

Decide whether a non-essential actor should be paused.
