Struct strict_num::PositiveF64

pub struct PositiveF64(/* private fields */);

An immutable, finite f64 that is known to be >= 0.

Implementations

impl PositiveF64

pub const ZERO: Self = _

A PositiveF64 value initialized with zero.

pub fn new(n: f64) -> Option<Self>

Creates a new PositiveF64 if the given value is >= 0.

Returns None for negative, NaN and infinity.

pub const unsafe fn new_unchecked(n: f64) -> Self

Creates a new PositiveF64 without checking the value.

Safety

n must be finite and >= 0.

pub const fn get(&self) -> f64

Returns the value as a primitive type.

pub const fn get_finite(&self) -> FiniteF64

Returns the value as a FiniteF64.

Trait Implementations

impl Clone for PositiveF64

fn clone(&self) -> PositiveF64

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

Performs copy-assignment from source.

impl Debug for PositiveF64

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

Formats the value using the given formatter.

impl Default for PositiveF64

fn default() -> PositiveF64

Returns the “default value” for a type.

impl Display for PositiveF64

impl Hash for PositiveF64

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 PositiveF64

fn cmp(&self, other: &PositiveF64) -> 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.

impl PartialEq<f64> for PositiveF64

fn eq(&self, other: &f64) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq for PositiveF64

fn eq(&self, other: &PositiveF64) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for PositiveF64

fn partial_cmp(&self, other: &PositiveF64) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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