Trait Unif01Ext 

pub trait Unif01Ext {
    // Required method
    fn unif_01(&mut self) -> f64;
}

Extension trait adding a unif_01 method to every generator implementing rand_core::Rng (in particular, to the generators of the rand crate).

Required Methods

fn unif_01(&mut self) -> f64

Returns a random f64 distributed as a uniform real in [0 . . 1) rounded down to the nearest representable value: every float in [0 . . 1) is reachable, subnormals and 0 included, with probability equal to the measure of the reals that round down to it.

This is f64_full applied to the generator.

Examples

use rand_float::uniform::Unif01Ext;

let x = rand::rng().unif_01();
assert!((0.0..1.0).contains(&x));

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
