Struct NotNan

pub struct NotNan<T>(/* private fields */);

The type used for float fields that are never NaN. A wrapper around floats providing an implementation of Eq, Ord and Hash.

A NaN value cannot be stored in this type.

use ordered_float::NotNan;

let mut v = [
    NotNan::new(2.0).unwrap(), 
    NotNan::new(1.0).unwrap(), 
];
v.sort();
assert_eq!(v, [1.0, 2.0]);

Because NotNan implements Ord and Eq, it can be used as a key in a HashSet, HashMap, BTreeMap, or BTreeSet (unlike the primitive f32 or f64 types):

let mut s: HashSet<NotNan<f32>> = HashSet::new();
let key = NotNan::new(1.0).unwrap();
s.insert(key);
assert!(s.contains(&key));

Arithmetic on NotNan values will panic if it produces a NaN value:

let a = NotNan::new(std::f32::INFINITY).unwrap();
let b = NotNan::new(std::f32::NEG_INFINITY).unwrap();

// This will panic:
let c = a + b;

Converts the value of self to an i16. If the value cannot be represented by an i16, then None is returned.

fn to_i32(&self) -> Option<i32>

Converts the value of self to an i32. If the value cannot be represented by an i32, then None is returned.

fn to_usize(&self) -> Option<usize>

Converts the value of self to a usize. If the value cannot be represented by a usize, then None is returned.

fn to_u8(&self) -> Option<u8>

Converts the value of self to a u8. If the value cannot be represented by a u8, then None is returned.

fn to_u16(&self) -> Option<u16>

Converts the value of self to a u16. If the value cannot be represented by a u16, then None is returned.

fn to_u32(&self) -> Option<u32>

Converts the value of self to a u32. If the value cannot be represented by a u32, then None is returned.

fn to_f32(&self) -> Option<f32>

Converts the value of self to an f32. Overflows may map to positive or negative inifinity, otherwise None is returned if the value cannot be represented by an f32.

fn to_f64(&self) -> Option<f64>

Converts the value of self to an f64. Overflows may map to positive or negative inifinity, otherwise None is returned if the value cannot be represented by an f64.

fn to_i128(&self) -> Option<i128>

Converts the value of self to an i128. If the value cannot be represented by an i128 (i64 under the default implementation), then None is returned.

fn to_u128(&self) -> Option<u128>

Converts the value of self to a u128. If the value cannot be represented by a u128 (u64 under the default implementation), then None is returned.
