Enum PressureLevel 

pub enum PressureLevel {
    Normal,
    Warning,
    Critical,
    Emergency,
}

Memory pressure level.

Variants

Normal

Normal operation (< 60% usage).

Warning

Warning level (60-80% usage). Non-essential allocations should be avoided.

Critical

Critical level (80-95% usage). Active mitigation required.

Emergency

OOM imminent (>95% usage). Emergency measures.

Implementations

impl PressureLevel

pub fn from_usage(fraction: f64) -> PressureLevel

Compute pressure level from usage fraction (0.0 - 1.0).

Trait Implementations

impl Clone for PressureLevel

fn clone(&self) -> PressureLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PressureLevel

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

Formats the value using the given formatter.

impl Display for PressureLevel

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

Formats the value using the given formatter.

impl Ord for PressureLevel

fn cmp(&self, other: &PressureLevel) -> 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 PressureLevel

fn eq(&self, other: &PressureLevel) -> 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 PressureLevel

fn partial_cmp(&self, other: &PressureLevel) -> 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.
