Struct ron::value::Float

source ·
pub struct Float(/* private fields */);
Expand description

A wrapper for f64, which guarantees that the inner value is finite and thus implements Eq, Hash and Ord.

Implementations§

source§

impl Float

source

pub fn new(v: f64) -> Self

Construct a new Float.

source

pub fn get(self) -> f64

Returns the wrapped float.

impl Debug for Float

source§

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

Formats the value using the given formatter. Read more
source§

impl Hash for Float

source§

1.3.0 · source§

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

Feeds a slice of this type into the given Hasher. Read more
source§

impl Ord for Float

Ordering comparison In order to be able to use Float as a mapping key, NaN floating values wrapped in Float are equal to each other and are less then any other floating value. It is not the case for underlying f64 values itself. See the PartialEq implementation.

source§

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other. Read more
1.21.0 · source§

fn max(self, other: Self) -> Self
where Self: Sized,

Compares and returns the maximum of two values. Read more
1.21.0 · source§

fn min(self, other: Self) -> Self
where Self: Sized,

Compares and returns the minimum of two values. Read more
1.50.0 · source§

fn clamp(self, min: Self, max: Self) -> Self
where Self: Sized + PartialOrd,

Restrict a value to a certain interval. Read more
source§

impl PartialEq for Float

Partial equality comparison In order to be able to use Number as a mapping key, NaN floating values wrapped in Float are equal to each other. It is not the case for underlying f64 values itself.

source§

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

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

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.
source§

impl PartialOrd for Float

Partial ordering comparison In order to be able to use Number as a mapping key, NaN floating values wrapped in Number are equal to each other and are less then any other floating value. It is not the case for the underlying f64 values themselves.

use ron::value::Number;
assert!(Number::new(std::f64::NAN) < Number::new(std::f64::NEG_INFINITY));
assert_eq!(Number::new(std::f64::NAN), Number::new(std::f64::NAN));
