[−][src]Enum ron::value::Number
A wrapper for a number, which can be either f64
or i64
.
Variants
Integer(i64)
Float(Float)
Implementations
impl Number
[src]
pub fn new(v: impl Into<Number>) -> Self
[src]
Construct a new number.
pub fn into_f64(self) -> f64
[src]
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>
[src]
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>
[src]
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
[src]
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));
