Struct DccContext 

pub struct DccContext {
    pub hardware: HardwareState,
    pub mode: EngineMode,
    pub global_budget_multiplier: f32,
    pub memory_pressure: f32,
}

The complete context model used for strategic decision making.

Fields

hardware: HardwareState

Observed hardware state.

mode: EngineMode

Current engine mode.

global_budget_multiplier: f32

Global budget multiplier applied to all frame budgets for graceful performance degradation. Ranges from 0.0 (emergency) to 1.0 (full performance).

Driven by the DCC’s frame-time PID controller (khora_core::control::pid), not a static table: the loop asservits this value so the measured frame time tracks the heuristic-suggested latency (AnalysisReport::suggested_latency_ms, itself modulated by thermal/battery/phase). On Critical thermal/battery or high memory pressure the DCC additionally clamps it to a hard safety ceiling.

memory_pressure: f32

System-memory pressure in [0, 1] — current_ram_bytes / memory_budget_bytes, or 0.0 when the budget is unset. A first-class resource signal alongside thermal/CPU/GPU: drives graceful degradation here and feeds the AGDF repack-headroom gate (a repack transiently doubles a column, so it is declined under high pressure).

Implementations

impl Context

pub fn refresh_memory_pressure(&mut self)

Recomputes Context::memory_pressure from the current RAM usage versus the developer-set budget.

Pressure is current_ram_bytes / memory_budget_bytes, clamped to [0, 1]. An unset budget yields 0.0 (the signal is inert). This is a first-class resource signal consumed by the heuristic engine and the AGDF repack gate; it no longer feeds the budget multiplier directly — that is the PID loop’s job — but it does drive the DCC’s hard safety clamp (see safety_ceiling).

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.
