# Enum ron::value::Number

source · [−]

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

Expand description

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

## Variants

### `Integer(i64)`

### `Float(Float)`

## Implementations

source

### impl Number

source

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

Construct a new number.

source

#### 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);

source

#### 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));

source

#### 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);

source

#### 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));
