Enum PressureAction 

pub enum PressureAction {
    None,
    SnipCompact,
    MicroCompact,
    ContextCollapse,
    AutoCompact,
}

Action recommended by the pressure monitor — the pressure-level vocabulary.

This is distinct from crate::mm::EvictionOp (the planner-op vocabulary) and the two must not be collapsed: PressureAction is what PressureMonitor::recommend / ContextManager::should_compress return, the Ord-keyed cascade selector inside the compression pipeline, and the canonical compaction wire label. EvictionOp is what plan_eviction emits, and carries per-op data this enum has no place for. The single bridge between the two layers is LoopStateMachine::execute_eviction_op. See the layer-boundary note on crate::mm::EvictionOp.

Implementations

impl PressureAction

pub fn label(self) -> &'static str

Canonical snake_case label — the single source for compaction-event action strings and the [Compressed: {label}] summary marker (used by both the summarizer and the compaction log).

Trait Implementations

impl Clone for PressureAction

fn clone(&self) -> PressureAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PressureAction

impl Debug for PressureAction

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

Formats the value using the given formatter.

impl Eq for PressureAction

impl From<PressureAction> for KernelPressureAction

fn from(action: PressureAction) -> Self

Converts to this type from the input type.

impl Ord for PressureAction

fn cmp(&self, other: &PressureAction) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PressureAction

fn eq(&self, other: &PressureAction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PressureAction

fn partial_cmp(&self, other: &PressureAction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
