Enum ZonePressure 

pub enum ZonePressure {
    Healthy,
    High,
    Low,
    Min,
}

Derived pressure state for a zone snapshot.

Thresholds are evaluated against the zone’s effective free pages, including pages parked in order-0 per-CPU caches.

Variants

Healthy

Free pages are above the high watermark.

High

Free pages dropped below the high watermark.

Low

Free pages dropped below the low watermark.

Min

Free pages reached the minimum watermark plus reserve floor.

Trait Implementations

impl Clone for ZonePressure

fn clone(&self) -> ZonePressure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ZonePressure

impl Debug for ZonePressure

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

Formats the value using the given formatter.

impl Eq for ZonePressure

impl PartialEq for ZonePressure

fn eq(&self, other: &ZonePressure) -> 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.
