Trait Float

pub trait Float:
    PartialOrd
    + PartialEq
    + FloatImpl {
    // Required method
    fn ord(self) -> OrderedFloat<Self>
       where Self: Sized;
}

Extension trait to provide ord() method.

Example with f64:

use emath::Float as _;

let array = [1.0, 2.5, 2.0];
let max = array.iter().max_by_key(|val| val.ord());

assert_eq!(max, Some(&2.5));

Required Methods

fn ord(self) -> OrderedFloat<Self>

where Self: Sized,

Type to provide total order, useful as key in sorted contexts.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types
