Struct Percent 

pub struct Percent(/* private fields */);

A percentage value in 0.0..=100.0.

Eq / Hash are deliberately not implemented (float comparison).

Implementations

impl Percent

pub const ZERO: Self

pub const HUNDRED: Self

pub fn new(value: f64) -> Self

Construct a percentage, clamping to [0, 100].

pub fn from_fraction(f: f64) -> Self

Construct from a fraction in [0, 1]. Percent::from_fraction(0.5) == 50%.

pub const fn as_percent(self) -> f64

Get the percentage as f64 in [0, 100].

pub fn as_fraction(self) -> f64

Get the percentage as a fraction in [0, 1].

pub fn as_kernel_probability(self) -> u32

Convert to the kernel’s 32-bit probability representation (used in netem qopt fields). Percent::HUNDRED -> u32::MAX.

pub fn is_zero(self) -> bool

Returns true if exactly zero.

Trait Implementations

impl Clone for Percent

fn clone(&self) -> Percent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Percent

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

Formats the value using the given formatter.

impl Default for Percent

fn default() -> Percent

Returns the “default value” for a type.

impl Display for Percent

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

Format as "<value>%" with reasonable precision.

impl FromStr for Percent

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse "50", "50%", "1.5%", or "0.5" (treated as a fraction).

type Err = PercentParseError

The associated error which can be returned from parsing.

impl PartialEq for Percent

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

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