Struct ThrottlePolicy 

pub struct ThrottlePolicy { /* private fields */ }

Maps (priority, pressure) pairs to throttle decisions.

Contains a list of thresholds: a task at or below a given priority (higher numeric value = lower priority) is throttled when pressure exceeds the associated limit.

Thresholds are evaluated from lowest priority to highest. The first matching rule applies.

Implementations

impl ThrottlePolicy

pub fn new(thresholds: Vec<(Priority, f32)>) -> Self

Create a policy with custom thresholds.

Each (priority, limit) means: any task with priority value >= priority (i.e. lower or equal priority) is throttled when pressure > limit.

Thresholds should be ordered from lowest priority to highest.

pub fn default_three_tier() -> Self

Default three-tier policy matching Shoebox’s original behavior:

• BACKGROUND (192+): pause at >50% pressure
• NORMAL (128+): pause at >75% pressure
• Everything else: never pause

pub fn should_throttle(&self, priority: Priority, pressure: f32) -> bool

Should a task at this priority be throttled given current pressure?
