Struct RationalRate 

pub struct RationalRate { /* private fields */ }

A positive, normalized rational rate.

Implementations

impl RationalRate

pub fn new(numerator: u32, denominator: u32) -> Result<Self>

Creates a reduced positive rate.

Errors

Returns ErrorKind::InvalidArgument when either component is zero.

pub const fn numerator(self) -> u32

Returns the reduced numerator.

pub const fn denominator(self) -> u32

Returns the reduced denominator.

Trait Implementations

impl Clone for RationalRate

fn clone(&self) -> RationalRate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RationalRate

impl Debug for RationalRate

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

Formats the value using the given formatter.

impl Display for RationalRate

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

Formats the normalized rate as numerator/denominator.

impl Eq for RationalRate

impl FromStr for RationalRate

fn from_str(value: &str) -> Result<Self>

Parses the canonical numerator/denominator representation.

type Err = Error

The associated error which can be returned from parsing.

impl Hash for RationalRate

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RationalRate

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

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

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