Configuration for widget refresh selection under render budget.

Defaults are conservative and deterministic:

• enabled: true
• staleness_window_ms: 1_000
• starve_ms: 3_000
• max_starved_per_frame: 2
• max_drop_fraction: 1.0 (disabled)
• weights: priority 1.0, staleness 0.5, focus 0.75, interaction 0.5
• starve_boost: 1.5
• min_cost_us: 1.0

Fields

enabled: bool

Enable budgeted widget refresh selection.

staleness_window_ms: u64

Staleness decay window (ms) used to normalize staleness scores.

starve_ms: u64

Staleness threshold that triggers starvation guard (ms).

max_starved_per_frame: usize

Maximum number of starved widgets to force in per frame.

max_drop_fraction: f32

Maximum fraction of non-essential widgets that may be dropped. Set to 1.0 to disable the guardrail.

weight_priority: f32

Weight for base priority signal.

weight_staleness: f32

Weight for staleness signal.

weight_focus: f32

Weight for focus boost.

weight_interaction: f32

Weight for interaction boost.

starve_boost: f32

Additive boost to value for starved widgets.

min_cost_us: f32

Minimum cost (us) to avoid divide-by-zero.
