Implementations§

Source §

impl NodeMemoryGovernor

Source

pub fn new(governor: MemoryGovernor) -> Self

Source

pub fn evaluate(&mut self, inputs: &NodePressureInputs) -> Vec<GovernorAction>

Evaluate inputs and produce ordered actions (escalation ladder).

Source

pub fn last_actions(&self) -> &[GovernorAction]
