Struct parse_mediawiki_sql::field_types::NotNan

#[repr(transparent)]
pub struct NotNan<T>(_);

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;
