Struct ScalingPressureConfig 

pub struct ScalingPressureConfig {
    pub enabled: bool,
    pub memory_gate_threshold: f64,
}

Available on crate feature scaling only.

Base configuration for scaling pressure calculation.

Lives in the app’s config cascade so thresholds are env-var overridable (e.g., DFE_LOADER__SCALING__MEMORY_GATE_THRESHOLD=0.9).

Component weights and saturation points are app-specific – defined in each app’s config and passed to super::ScalingPressure::new via ScalingComponent.

Fields

enabled: bool

Enable scaling pressure calculation. When disabled, calculate() always returns 0.0.

memory_gate_threshold: f64

Memory usage ratio that triggers the memory gate (0.0-1.0).

When memory_used / memory_limit >= threshold, scaling pressure is forced to 100.0 to trigger immediate scale-up before OOM.

Implementations

impl ScalingPressureConfig

pub fn from_cascade() -> Self

Load from the config cascade under the scaling key.

Falls back to ScalingPressureConfig::default() if config is not initialised or the key is absent.

Trait Implementations

impl Clone for ScalingPressureConfig

fn clone(&self) -> ScalingPressureConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalingPressureConfig

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

Formats the value using the given formatter.

impl Default for ScalingPressureConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScalingPressureConfig

where ScalingPressureConfig: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ScalingPressureConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
