Enum bevy::asset::ron::value::Number

pub enum Number {
    Integer(i64),
    Float(Float),
}

A wrapper for a number, which can be either f64 or i64.

Variants

Integer(i64)

Float(Float)

Implementations

impl Number

pub fn new(v: impl Into<Number>) -> Number

Construct a new number.

pub fn into_f64(self) -> f64

Returns the f64 representation of the Number regardless of whether the number is stored as a float or integer.

Example

let i = Number::new(5);
let f = Number::new(2.0);
assert_eq!(i.into_f64(), 5.0);
assert_eq!(f.into_f64(), 2.0);

pub fn as_f64(self) -> Option<f64>

If the Number is a float, return it. Otherwise return None.

Example

let i = Number::new(5);
let f = Number::new(2.0);
assert_eq!(i.as_f64(), None);
assert_eq!(f.as_f64(), Some(2.0));

pub fn as_i64(self) -> Option<i64>

If the Number is an integer, return it. Otherwise return None.

Example

let i = Number::new(5);
let f = Number::new(2.0);
assert_eq!(i.as_i64(), Some(5));
assert_eq!(f.as_i64(), None);

pub fn map_to<T>( self, integer_fn: impl FnOnce(i64) -> T, float_fn: impl FnOnce(f64) -> T ) -> T

Map this number to a single type using the appropriate closure.

Example

let i = Number::new(5);
let f = Number::new(2.0);
assert!(i.map_to(|i| i > 3, |f| f > 3.0));
assert!(!f.map_to(|i| i > 3, |f| f > 3.0));

Trait Implementations

impl Clone for Number

fn clone(&self) -> Number

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl From<f64> for Number

fn from(f: f64) -> Number

Converts to this type from the input type.

impl From<i32> for Number

fn from(i: i32) -> Number

Converts to this type from the input type.

impl From<i64> for Number

fn from(i: i64) -> Number

Converts to this type from the input type.

impl From<u64> for Number

The following Number conversion checks if the integer fits losslessly into an i64, before constructing a Number::Integer variant. If not, the conversion defaults to Number::Float.

fn from(i: u64) -> Number

Converts to this type from the input type.

impl Hash for Number

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

where __H: Hasher,

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 Number

fn cmp(&self, other: &Number) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Number

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

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