Struct rand::Open01

pub struct Open01<F>(pub F);

A wrapper for generating floating point numbers uniformly in the open interval (0,1) (not including either endpoint).

Use Closed01 for the closed interval [0,1], and the default Rand implementation for f32 and f64 for the half-open [0,1).

Example

use rand::{random, Open01};

let Open01(val) = random::<Open01<f32>>();
println!("f32 from (0,1): {}", val);
