Function usize 

pub fn usize() -> Usize

Create a new usize mutator.

Example

use mutatis::{mutators as m, Mutate, Session};

let mut mutator = m::usize();

let mut session = Session::new().shrink(true);

let mut value = 42;
session.mutate_with(&mut mutator, &mut value).unwrap();

assert!(value < 42);
